Finite Volume Analysis of Artificially Roughened Solar Duct with Arbitrary Relative Gap Width and Profile
-Vijay Kumar ; Vijay Kumar; Anil Kumar Rao; Vinay Yadav
As the Solar effects continues to work at a rapid pace, it begins to generate heat. If this heat is not kept in check, the space could overheat and eventually increases itself. Fortunately, a cooling space include a solar duct, which dissipates the heat from the space, preventing it from overheating with the increase in heat dissipation from space and the reduction in overall form factors, thermal management becomes a more and more important element of solar duct product design. Both the performance reliability and life expectancy of solar duct are inversely related to the component temperature of the system. The relationship between the reliability and the operating temperature of a typical aluminum solar duct with artificial roughness component shows that a reduction in the temperature corresponds to an exponential increase in the reliability and life expectancy of the system. Therefore, long life and reliable performance of a component may be achieved by effectively controlling the solar duct operating temperature within the limits set by the device design engineers.

Simulation Analysis of Proton Exchange Membrane Fuel Cell (PEMFC) by using Computational Fluid Dynamics
-Manjunath A Dhadke ; M. R. Nagaraj
A full three-dimensional, single phase computational fluid dynamics model of a proton exchange membrane fuel cell (PEMFC) with both gas distribution flow channels and Membrane Electrode Assembly (MEA) has been developed. A single set of conservation equations which are valid for the flow channels, gas-diffusion electrodes, catalyst layers, and the membrane region are developed and numerically solved using a finite volume based computational fluid dynamics technique. In this research, some parameters such as oxygen consumption, water production, temperature distribution, ohmic losses, anode water activity, cathode over-potential and the fuel cell performance for straight single cell were investigated in more detail. The numerical simulations reveal that these important operating parameters are highly dependent on each other and the fuel cell efficiency is affected by kind of species distribution. 3D computational model for proton exchange membrane (PEM) fuel cells has been developed, and implemented into a computational fluid dynamic (CFD) code. The model allows parallel computing, thus making it practical to perform well-resolved simulations for large computational domains. So for, especial uses in desirable voltages, for preventing from the unwilling losses, these numerical results can be useful. Read More...

A Review Paper on Different Effects of Artificial Neutral Network on Prediction of Various Properties of Soil Used in the Construction
-Apoorv Purohit
This project generally deals with the study of the properties of black cotton soil that has extraordinary and uncertain behaviours which are due to its complex and indefinite physical processes that are associated during the formation of various materials. In this project, we are dealing with the complexities that are exhibited considering the geotechnical behaviour. The uncertainties that the geotechnical engineers are confronted with are mainly inconsistency, loading effects, timing effects, construction effects, and errors in soil boring. An engineer has to be skilled and competent to interpret the results of the laboratory tests for applying it in the field. Hence, to cope up with solving some of the geotechnical problems, the traditional engineering modelling techniques that cannot interpret the results accurately has been replaced with the Artificial Neural Networks (ANN). The ANN model utilizes the ANN tool in the MATLAB software. The data presented to the neural network through the input layer has given response through output layer after passing through the hidden layers. The intermediary layers or the hidden layers are locations where complicated problems are linked with input and output. These hidden layers provide the network with high degree of non-linearity. Through the application of ANN the properties of soil like the compression index, shear strength, permeability, soil compaction, lateral earth pressure, etc. are estimated. These are mainly influencing factors for describing the interaction of soil with the other earth materials during the construction phase which leads to the success, economy and safety of work. To overcome some of the complex issues that are associated with black cotton soil, properties like Liquid Limit, Plasticity Index, Maximum Dry Density and optimum Moisture content have been also studied.

Improved version of HALO: Hop-by-Hop Adaptive Link State Optimal Routing with 2Ack System
-Anup Subhashrao Patil
Use of HALO scheme to achieve finest routing is newly developed better approach. By using the technique every node, for every other node, the algorithm independently and iteratively updates the fraction of traffic destined to that leaves on every of its outgoing links. At every iteration, the updates are calculated by using on the shortest path calculations to each destination which in turns determined by the marginal costs of the network’s links. That means the marginal link costs are used to find the shortest paths are in turn obtained from link-state updates that are flooded through the network after every iteration. This technique is also adaptive which means it automatically detects the static network changes and takes decisions considering the other available means. Though this has achieved to eliminate the trade-off between optimality and ease of implementation and routing still it can work elegantly if we tried to reduce the acknowledgement overhead traffic. This paper project that there is a congestion issue due to acknowledgements which is to be reduced by using 2ACK system with triplet model and this has helped to reduce traffic and improve link utilization. This paper also gives experimental results to support these theoretical facts. Read More...

Seismic Vulnerability Assessment of RC Buildings with Plan Irregularities using Pushover Analysis
-Shilpa Haranagera ; Shridevi Angadi
Earthquakes are the most dangerous and unpredictable forces in nature. Seismic behaviour of structures is always an area of concern and requires special attention from structural designers. Presence of plan and vertical irregularities further complicates the seismic behaviour of the structures and also makes the structures more vulnerable to seismic forces. Pushover analysis, which is gaining popularity as an effective tool to quantify the seismic vulnerability of structures, is a good method of analysis to deal with structures with irregularities. In the present study, an attempt is made to study the seismic vulnerability of buildings with plan irregularities using pushover analysis. In the present study 3 storey, 6 storey and 9 storey structures of regular configurations as well as varying amount of irregularities has been modelled and analysed. ETABS, an efficient FE analysis tool, has been used for the analysis. The modelling and loading considerations are according to relevant Indian codes while pushover analysis has been carried out according to FEMA and ATC codes. The parameters compared involve base shear carrying capacity, displacement capacity, performance point and the status of hinges formed. An attempt was also made to study and quantify the improvement in the seismic capacity of the structure by strengthening it using shear wall elements. The results of the analysis revealed that the structures with plan irregularity are more vulnerable to seismic forces compared to regular structures. Irregular structures possessed much lower base shear capacity compared to regular structures and the states of hinges formed were also at higher damage states. The introduction of shear walls proved to be an effective solution against the plan irregularity. The structures strengthened with shear walls exhibited tremendous improvement in the base shear carrying capacity (3 to 5 times) and also overall ductility of the structures. The improved states of hinges formed during pushover analysis also indicated the lesser vulnerability of irregular structures with shear walls. Read More...

Design and Analysis of Automobile Chasis sing F.E.A
-Salman Khan ; Ritesh Banpurkar
The portable toilets are mounted on the chassis, this chassis is manufactured by a company (ExcellFibrotech, MIDC Nagpur). Many of new product designs are based on existing products and years of experience. Therefore, the chassis is assumed to have unexplored areas of potential improvements. Today the chassis is mainly a welded design, which is both expensive and unsatisfactory from a maintenance viewpoint. Welding is not only expensive but introduces heat to the steel alloy, and thereby changes the material properties, and also requires a high degree of manual labor. A truck chassis has a more standardized manufacturing method and application of some of the manufacturing techniques from it to the chassis could perhaps make the production of it more efficient. The current chassis have robust designs, and there have been no actual calculations or investigation to find out what dimensions are needed to withstand the forces applied to a chassis during use. Instead, the design is based on experience of what works, and what does not. A more thorough investigation of the design parameters can create better understanding of which parts of the chassis that are most exposed to high stresses, and which parts that can have reduced dimensions.

Big Data Processing: Improve Scheduling Environment in Hadoop
-Joshi Bhavik Bipinkumar
Now a days, dealing with datasets in the order of terabytes or even petabyte is a reality. Therefore, processing such big datasets in an efficient way is a clear need for many users. In this context, Hadoop Map Reduce is a big data processing framework that has rapidly become the de facto standard in both industry and academia. The main reasons of such popularity are the ease-of-use, scalability, and failover properties of Hadoop Map Reduce. However, these features come at a price: the performance of Hadoop Map Reduce is usually far from the performance of a well-tuned parallel database. Therefore, many research works (from industry and academia) have focused on improving the performance of Hadoop Map Reduce jobs in many aspects. For example, researchers have proposed different data layouts; join algorithms, high-level query languages, failover algorithms, query optimization technique, and indexing techniques. We will point out the similarities and differences between the techniques used in Hadoop with those used in parallel databases. And try to improving scheduling environment in Hadoop. Read More...

Faliure analysis of drive shaft using fea
-Abhinesh Aswar ; ritesh banpurkar
Drive shaft is a mechanical link of transmission system which is used to transfer the power from engine to the drive wheel. It comprises two main components joints and the actual shaft is almost universally used in front wheel drive (FWD) vehicles. The use of drive shaft as a power transmitter in automobile is more convenience because it is less likely to become jammed or broken as compared to chain-drives assembly. In operation, drive shaft is generally subjected torsional and bending stresses due to which fatigue and fracture failures may occur. Some common causes of failures are design, manufacturing, raw material, maintenance and the user originated faults. In this project the drive shaft of Maruti Alto car was investigated for failures. Considering the system, torque acting on a shaft used to calculate the Stress analysis by using FEA and the results compared with the calculated values. The stress in the shaft was exceeding the endurance limit of 70Mpa, the shaft may have failed prematurely due to fatigue loads before the average life of car. Thus it was important to redesign the shaft so that the induced stress is less than the endurance limit of 70Mpa. Read More...

-Tanzeela Khanam ; Pravin S.Metkewar
The development of Data Warehouse starts with requirements gathering, designing the dimensional model which is further followed by testing and maintenance. It is the central repository where all the historical data is stored and maintained which is further used for the analysis. The most important activity in building of a data warehouse successfully is design phase. This work presents a brief description of different architectural approaches and techniques that address the DW Design problem. Different data models have been proposed for data warehouse design but these approaches are based on their own visual modeling languages UML or ER model, and there is no standard method or model that allows us to model all aspects of a DW. There are four stages of data migration in the proposed model: Data extraction, cleansing and refining data, data transforming, data indexing and loading which is further explained in the paper. Also this work presents the brief description of different approaches and techniques that addresses the DW Architecture. This paper shows the typical data warehouse architecture for different level: one, two, three level classical and novel three level architecture. The proposed architecture exhibits some drawbacks at the point when connected to work over extensive number of heterogeneous data sources. Read More...

Optimum Selection of Electric ARC Welding Parameters Using AHP Method
-Rajesh Kumar Patel
Optimization is the discipline of adjusting a process so as to optimize some specified set of parameters without violating some constraint. The most common goals are minimizing cost and maximizing efficiency. This is one of the major quantitative tools in industrial decision making. When optimizing a process, the goal is to maximize one or more of the process specifications, while keeping all others within their constraints. AHP is a well-established decision making process. Therefore, AHP can help in the decision making process for the identification of the EAW parameters. The AHP method has the ability to structure complex, multi-person, multi-attribute, and multi-period problem hierarchically. Pair wise comparisons of the element (usually, alternatives and attributes) can be established using a scale indicating the strength with which one element dominates another with respect to a higher-level element. The main objective of this of this paper is to develop the relationships among the identified EAW parameters using AHP and pair wise comparisons of the element (usually, alternatives and attributes) can be established then can be translated into priority weights (scores).

Geomorphology of the Coast between Koteshwar to Jakhau (Kori Creek), Kachchh, Western India
-Nishith Y. Bhatt ; Heman V. Majethiya; Paras M. Solanki; -; -
Study of coastal geomorphology of the Kori creek coast between Koteshwar to Jakhau has been carried out. Diverse geomorphic features of submergence are found here like incised river deltas, sea cliffs superimposed by geomorphic features of emergence like inshore crescent barrier beaches, fore dunes, tidal creeks, tidal mud flats, parabolic dunes, lagoons, saline sand flats, mangroves etc. The superimposition of emergent features on submergent features suggests an emergent coast of the recent time on the submerge coast of the past. Such complex superimposition has developed due to the movements along hinge zone of Kachchh lying between Patcham island to Mandvi, running almost in N-S direction which was elevated towards east and subsided towards west, during past time, along with tectonic movements on E-W trending faults like Kachchh Mainland Fault (KMF) and Katrol Hill Fault (KHF) in Kachchh, which results into emergent features of the recent time in the study area.

Seismic Evaluation of Multi Storeyed Building on A Sloped Ground.
-Kazi Md Zaheeruddin ; Prof. Nadeem Pasha
Most of the hilly regions of India are highly seismic. Buildings on hill slopes differ in a way from other buildings. The various floors of such building steps back towards the hill slope and at the same time buildings may have setbacks also. Due to varied configurations of buildings in hill areas, these buildings become highly irregular and asymmetric. Buildings situated in hilly areas are much more vulnerable to seismic environment. The performance of structures during past earthquakes has shown that asymmetric-plan buildings are especially vulnerable to earthquake damage. In this study, 3D analytical model of 13 storied Ascending & Descending slope buildings have been generated & analyzed using structural analysis tool ‘ETABS Non-linearâ€. To study the effect of infill and concrete core wall during earthquake, seismic analysis using both linear dynamic (response spectrum method) as well as non-linear static procedure (pushover) has been performed. From the above studies it has been observed that nonlinear pushover analysis provide good estimate of global as well as local inelastic deformation demands and also reveals design weakness that may remain hidden in an elastic analysis. Storey drifts are found within the limit as specified by code (IS: 1893-2002 part-1) in both linear dynamic and non-linear static analysis. Read More...

Comparative Performance of Reheat and Regenerative Steam Cycle by using Program
-Kiran ; Prof. M R Nagaraj
The present paper describes performance comparison of reheat cycle and regenerative steam power cycle. Thermal efficiency calculation is carried out by developing a program using c language. Using this developed program we can analyze steam power cycles such as simple rankine cycle, reheat cycle, regenerative cycle and combined reheat and regenerative cycle for different process parameters. Developed program takes into account isentropic efficiency of turbine and pump. Inlet and outlet pressure, temperature of boiler, turbine, pump and condenser. Comparison between rankine cycle, reheat cycle, regenerative cycle and combined cycle are made at different operating conditions. Small increment in thermal efficiency leads to large investment return and more power production for a given set of operating parameters. Developed program helps in determining thermal efficiency of the cycle by choosing appropriate set of operating condition of process parameters. This analysis helps power plant designers in choosing appropriate thermal power cycle for a given set of operating conditions. It is observed that the results obtained from the program, such as optimum bled steam tapping pressure for regenerative cycle and effect of boiler pressure variation on reheat cycle and regenerative cycle are in good agreement with the referred literature. Analysis shows that regenerative cycle is more efficient compare to reheat cycle for a given set of operating conditions. Read More...

-Heman V. Majethiya ; Nishith Y. Bhatt ; Paras M. Solanki
Coastal geomorphological study of the Kori creek coast between Lakhpat and Koteshwar has been carried out. Various geomorphic features of submergence are found here such as incised river deltas, sea cliffs, stumps and platforms super-imposed by geomorphic features of emergence like inshore crescent barrier beaches, fore dunes, tidal creeks, tidal mud flats, parabolic dunes, lagoons, saline sand flats, mangroves etc. The super-imposition of features of emergence on features of submergence suggests an emergent coast at the present day on the submerge coast of the past. Such complex superimposition has occurred due to the movements along hinge zone of Kachchh lying between Patcham island to Mandvi, running almost in N-S direction which was emerged towards east and submerged towards west, during past time, along with tectonic activities on E-W trending faults like Kachchh Mainland Fault (KMF) and Katrol Hill Fault (KHF) in Kachchh, which results into emergent features of the recent time in the area investigated.

Investigation on 3-D Wing of commercial Aeroplane with Aerofoil NACA 2415 using CFD Fluent
-Rohit Jain ; Mr. Sandeep Jain; Mr. Lokesh Bajpai
An aerofoil is a cross-section of wing that plays an important role in any aeroplane or aircraft for designing the wings because of wings, lift is generated that holds the aircraft in the air. The design of wing with desired aerodynamic characteristics are most important for aircraft like fighter plane, commercial plane, UAV and MAV . The National Advisory Committee for Aeronautics (NACA) has given a proper definition for aerofoils which help us to select aerofoil for designing the wings of aeroplanes. In this work, NACA 2415 aerofoil has been chosen for designing the 3-D wing of commercial aeroplane because of its high lift to drag ratio at low Reynolds number and Mach number. The 3-D wing has chord length 100mm at root & 18mm at tip and span length 177 mm with 60 dihedral angle. Other wings also drawn with change in design of wing with profile (root) and dihedral angle. Spalart-Allamaras turbulence model is used for better accuracy around boundary wall of wing. Investigation on commercial aeroplane 3-D wing designs are investigated to study the Drag coefficient (CD), Lift coefficient (CL) and Lift-to-Drag ratio (L/D) at various angle of attack. The investigation aims to produce better aerodynamic performance for wing designs to reduce the induced drag formed on wing during the flight operation at take-off; in-turn it will improve the efficiency of the aircraft. The geometry of wing models and meshing are carried out by ANSYS 15 software. The computational simulation is carried out by ANSYS FLUENT at low Mach number (0.23). Flow parameters are measured for different design configurations and compared for efficient design. Read More...

Fabrication And Testing Of Biodegradable Fiber Composites
-HASSANKUTTY KP ; JITHESH NP
Glass fibers are the most useful reinforcement material in composites. The interest in using natural fibers such as different plant fibers and wood fibers as a substitute for glass fibers has increased during last few years. Natural fibers have many advantages compared to glass fibers, for example they have low density, and they are recyclable and biodegradable. Additionally they are renewable raw materials and have relatively high strength and stiffness. The effect of ply orientation on mechanical properties of reinforced natural composites like sisal fiber, kuruthola fiber, and banana fiber, is tested. In which the fibers are heat treated for enhancing the strength by removing moisture. Samples of deferent orientation of sisal fiber, kuruthola fiber, and banana fiber reinforced composites were fabricated. In this work the composite material is prepared from weight ratio of resin to mat is 3:1, for every 1kg of mat 3kg of polyester resin is used and for 100ml of resin 10ml of accelerator is used and ten drops of methyl ethyl ketone peroxide is used as catalyst to improve the speed of the reaction. The natural fiber composites like sisal fiber, banana fiber, and kuruthola fiber composites reach the mechanical properties of glass fiber composites and also in which 900 orientation (unidirectional) good mechanical properties than 450 orientations have. Due to the low density, bio degradability, and high specific properties natural fiber composite have very good future applications in modern industry. Read More...

Parametric Study on the Behavior of Raft Foundation for an Irregular High-Rise Building
-Prof. Rajendra J. Thakai ; Purushottam Poojari; R.D. Deshapande
Raft-foundation is obligatory where soils have low bearing-capacity and when they have to support substantial structural loads. Usually structures on marshy-land, soft-clay and land that are made-up of sanitary land-fill or other materials necessitate raft-foundation. Raft-foundations are usually favored in the soil that are assumed to undergo subsidence. Raft-foundation is the economical solution where deep-foundation like pile-foundation are not economical and reasonable and isolated-column footing is unpractical due to large footing size or over lapping of neighbor footing. In this project a 20 storeyed building is selected which is irregular in shape. The superstructure is modelled and analysed using ETABS software. The type of the foundation is selected for this study is Raft foundation and it’s modelled and analysed using SAFE software. In the parametric study, thickness of the raft is varied (1250 mm and 1750 mm) and its effect on maximum settlement, maximum bending moment and maximum shear force and soil pressure is observed.

Experimental investigation and Aerodynamic shape Optimization of an Aircraft
-Ankit Bhasin ; Dilip G. Gangwani
Continuous pressure to achieve reductions in direct operating cost (D.O.C.) combined with ever tightening environmental constraints has left aircraft designer with little option but to explore the possibilities offered by more novel configurations. The constant need to improve aerodynamic efficiency of an aircraft is one of the challenges in the aerospace field. This lead to the invention of various technologies like wingtip devices (called winglets), Blended-wing Body Aircraft (BWB), etc. The thorough study of present designs of Aircraft body for air flow velocity, induced drag lift & inventions like; Winglets & Blended-Wing Body aircraft, for design errors or to look for improvement that affects the efficiency. The blended-wing body is an aircraft configuration that has the potential to be more efficient than conventional large transport aircraft configurations with the same capability. However, the design of the blended-wing is challenging due to the tight coupling between aerodynamic performance, trim, and stability. Other design challenges include the nature and number of the design variables involved, and the transonic ow conditions. To address these issues, we perform a series of aerodynamic shape modification studies using Reynolds-averaged Naiver Stokes computational fluid dynamics with a turbulence model. A gradient-based modification is used in conjunction with a discrete adjoin method that computes the derivatives of the aerodynamic forces. A total of design variables angle of attack, air foil shape, chord, and span, structural load, dynamic loading |are considered. The drag coefficient at the cruise condition is minimized subject to lift, trim, static margin, and Centre plane bending moment constraints. The studies investigate the impact of the various constraints and design variables on optimized blended-wing-body configurations. The lowest drag among the trimmed and stable configurations is obtained by enforcing a 1% static margin constraint, resulting in a nearly elliptical span wise lift distribution. Trim and static stability are investigated at both on- and design flight conditions. The single-point designs are relatively robust to the flight conditions, but further robustness is achieved through a multi-point modification. The result of the study will be applied & the modelling of the improved design will be done & this design will be verified by analysis both with Static & Dynamic Simulation. Final results will provide the new improved design aspects for efficiency improvement. Read More...

Two-Tier Energy-Efficient Secure Scheme for Wireless Sensor Networks
-Deepa R.K ; Sreevidya R. C
Wireless Sensor Network (WSN) is mainly concerned with energy efficiency and security. Power exhausting attacks such as denial of sleep shortens the lifetime of WSN rapidly. Some of the MAC protocols are proposed to protect the sensor networks and extend its lifetime. The existing security mechanism awakes the sensor nodes before the security processes are allowed to execute. The work aims to authenticate the process by reducing the energy consumption of sensor nodes and enhances the performance of MAC protocols for power exhausting attacks. The scheme aims at replaying the attack in an efficient way. The reduced energy consumption is the coordination between energy conserved and security requirements for the sensor network application. The elaborated analysis of energy distribution shows a reasonable decision rule for coordination between energy conserved and security needs for wireless sensor networks. By combination of low complex secure method and multiple check points, the proposed design can defense against DOS attacks. Read More...

Reusing Construction Waste Towards Sustainable Building Construction and Its Effect for Composite Climate
-Chetan Santosh Dhanjode
Construction Industry is highly employment intensive and accounts & the projected investment in this industrial sector continues to show a growing trend. Construction activity leads to generation of solid wastes, which include sand, gravel, concrete, stone, bricks, wood, metal, glass, plastic, paper etc. The management of construction and demolition waste is a major concern for town planners due to the increasing quantum of demolition’s rubble, continuing shortage of dumping sites, increase in transportation and disposal cost and above all growing concern about pollution and environmental deterioration. Construction waste is bulky and heavy and is mostly unsuitable for disposal by incineration or composting. The growing population in the country and requirement of land for other uses has reduced the availability of land for waste disposal. Re-utilization or recycling is an important strategy for management of such waste. Apart from mounting problems of waste management, other reasons which support adoption of reuse/ recycling strategy are- reduced extraction of raw materials, reduced transportation cost, improved profits and reduced environmental impact. Above all, the fast depleting reserves of conventional natural aggregate has necessitated the use of recycling/ re-use technology, in order to be able to conserve the conventional natural aggregate and other material for other important works. Many opportunities exist for the beneficial reduction and recovery of materials that would otherwise be destined for disposal as waste. Construction industry professionals and building owners can educate and be educated about issues such as beneficial reuse, effective strategies for identification and separation of wastes, and economically viable means of promoting environmentally and socially appropriate means of reducing total waste disposed. Hence managing waste means eliminating waste where possible; minimizing waste where feasible; and reusing materials which might otherwise become waste. Solid waste management practices have identified the reduction, recycling, and reuse of wastes as essential for sustainable management of resources. The paper provides an overview and statistics of construction and demolition waste of the construction industry in India. Read More...

-Sambodhi D. Haste ; Abhay Satmohankar
This paper presents a real-time biomedical data compression and transmission for remote patient monitoring system. This algorithm contains five compression and four decompression procedures. For evaluating the performance of the algorithm, EEG signal taken from MIT-BIH arrhythmia database, and compress and transmit signal and checking it’s performances using evaluation parameters, compress ratio, percent root mean square difference normalized, signal noise ratio, and quality score. Result of the evaluation parameter gets better at 15% window size with high compression ratio 18.36 and percent root mean square difference 2.25. Performance of this algorithm was found better than the similar algorithms introduced recently, and having better compression ratio than other proposed algorithm. This algorithm showed superior performance in all data instances where compression ratio is lower or equal to 15:1 but it shows slightly inferior PRD performance where compression ratio is greater than 15:1. Similarity with the original data becomes meaningless when the PRD is higher than 2, this proposed algorithm shows significantly better performance compared to the performance l of the other algorithms. Moreover, because the algorithm can compress and transmit data in real time. So, it can be served as a biosignal data transmission method for limited bandwidth communication for remote patient monitoring system. Read More...

Experimental Study on the Strength Parameters of Concrete Confined with GFRP and CFRP
-SYED SAFEER AHMED ; Vasudev M.V
Fiber reinforced polymer (FRP) laminates are extensively used in retrofitting and strengthening of structures. The use of FRP is superior to the conventional method of steel jacketing in connection with strength of the retrofit, resistance to corrosion, ease of application, and also from the economic considerations, post confinement ductility, sectional area & weight. Retrofitting is done by winding of fibers & epoxy is used to bind the FRP laminates. FRP is extensively used in the united states, japan and recently it has got some recognition in India also. In spite of the wide variety of uses, basic aspects of FRP confined concrete is not understood quite well. Experimental investigation focuses on the strength parameters such as flexural strength and compressive strength of FRP confined concrete. The parameters varied in this investigation are type of fibers (CFRP or GFRP), number of plies, sequence of plies and curing period (7 days and 28 days water curing). As per the experimental investigation it is found that concrete specimens confined with CFRP have higher compressive and flexural strength for both single ply and double ply than the specimens confined with glass fiber (GFRP) after 7 days and 28 days of water curing.

Review on Effect of Steel Fibres and Glass Fibres on Self Compacting Concrete
-SHIVARAJ KUMAR H S ; Ashwini B T; CHETHAN V R; Dr.M.Ramegowda
The present article present brief review regarding the behaviour of self-compacting concrete with the addition of steel fibres and glass fibres. Self-compacting concrete (SCC) is a concrete which compact and settle by its own weight thereby smooth finishing can be achieved within a confined formwork. In structural members with high percentage of reinforcement, it fills also completely all voids and gaps. The past study place emphasis mainly on, the fresh and hardened properties of fibre reinforced concrete. Fresh properties include flow ability, passing ability and viscosity related segregation resistance. Hardened properties include compressive strength, splitting tensile strength, flexural strength, modulus of elasticity, and Ultrasonic pulse velocity. The results indicated of the fresh properties of SCC with steel fibre, reduction in workability with increase of steel fibres content. Self-compacting concrete with the addition of steel fibres shows enhanced tensile strength, flexural strength, and resistance to impact, fatigue and ductility, volumetric changes and effectiveness to aggressive environment with respect to ductility. Also with respect to the surface finishing SCC proved to be good when compare to any other type of concrete. Read More...
