Study of Utilization of GGBS in Cement Concrete

The use of supplementary cementitious materials is well accepted because of the several improvements possible in the concrete mix, for overall economy. The present work is a support to use the waste product from steel industry is helpful in cement which also helps to reduce the carbon footprint. In recent years Blast Furnace Slag when replaced with cement has emerged as a major alternative to conventional concrete and has rapidly gain the concrete industry’s attention due to its cement savings, energy savings, cost savings, socio-economic and environmental benefits. The present study reports the results of an experimental study, conducted to evaluate the strengths and strength efficiency factors of hardened concrete, by partially replacing the cement by various percentages of ground granulated blast furnace slag. The optimum GGBS replacement as cementitious material is characterized by high compressive strength, low heat of hydration, resistance to chemical attack, better workability, good durability and cost-effective. The vision of being a developed nation is today’s scenario wherein considering the lowest level of individuality; everyone is focused towards ones benefits rather being philanthropists. The field of concrete technology runs in the same track wherein lot of advancement has come in where still basics play the major role. The changes adopted with respect to construction and building materials made a scope for change in the traditional way of concrete and bitumen. This is a study based on effects of Admixtures on concrete; where in the natural behavior of such is compared to that of changes in their behavior when such substances are added. It definitely causes an impact to its physical, material and characterized properties, but its implementation to the advantage of human environment makes a sensible part wherein the adverse effects are either reduced or omitted dependently. Most of the construction companies today prefer RMC from Concrete mix plants being transported to sites adding to an advantage of suitable properties of the concrete as required. Ground Granulated Blast Furnace Slag is taken as admixture used in the concrete of respective grading and following its suitability for various purposes is categorized depending upon the results obtained. In this work we are going to study the effects of GGBS on the compressive strength of the cements concrete by replacing cement with GGBS by 10%, 15%, 20%, and 40%. This project work also includes the benefits of using GGBS and its effects on the cement and concrete properties and its durability, and its sustainability. The utilization of supplementary cementitious materials is well accepted because of the several improvements possible in the concrete composites, and due to the overall economy. This report introduces studies and the properties of ground granulated blast furnace slag (GGBS). As concrete being important constituent in construction industry, improvements need to be done in concrete. Use of GGBS improves the quality of concrete. GGBS concrete is characterized by high strength, lower heat of hydration, and resistance to chemical corrosion. In recent years GGBS when replaced with cement has emerged as a major alternative to conventional concrete and has rapidly drawn the concrete industry attention due to its cement savings, energy savings, and cost savings, environmental and socio-economic benefits. The optimum GGBS replacement as cementitious material is characterized by high compressive strength, low heat of hydration, resistance to chemical attack, better workability, and good durability and cost-effective. From this study it can be concluded that, since the grain size of GGBS is less than ordinary Portland cement, its strength at early ages is less but continues to gain strength over a long period. This report includes effect of GGBS on various physical and chemical properties of concrete. Low carbon concrete (LCC) can be produced by replacing OPC with GGBS thus reducing emission of carbon dioxide by about 60% and at the same time quality of concrete is improved.
