Review on Strength and Durability Investigations on High Performance Concrete Using Recycled Aggregate

Environmental friendly erection, sustainable or durable construction and conservation of natural resources are the three important essences of any modern development sector. However, construction of High performance concrete by using recycled concrete aggregate meets all of the above criteria to fulfil our needs. Recycled concrete aggregates have been widely studied in recent years, and reported as a suitable alternative for natural coarse aggregate. For the above essence, the utilization of recycled aggregate concrete in construction field is one such attempt. The use of recycled aggregates from demolished constructions as a natural aggregate for concrete becomes a need to reduce the economy of construction & study the effect of using recycled aggregates as natural aggregate for high-strength concrete on the main properties of high-strength concrete, however the use of recycled aggregate is restricted in lower grade erecting applications because of its strength and durability factor. The aim for this project is to investigate the strength and durability of high performance concrete by using recycled aggregates, which will give a better understanding on the properties of concrete with recycled aggregate. Now the test where conducted by replacing the natural aggregate with the recycled aggregate in the proportion of mixes by 0, 10, 20, 30, percentage, to get the comparative conclusion of different percentage. The concrete made of such strength uses Fly Ash, Recycled Aggregates and Super plasticizers that enhance the concrete properties and finally, the study summarizes the results of workability, durability, compressive strength and flexural strength which are very encouraging and it gives a new spectrum for the use of recycled aggregates in modern high performance concrete.
