SOME STUDIES ON STRENGTH BEHAVIOR OF RECYCLED AGGREGATE CONCRETE

Shivanand, H.S. Vidyadhar

Abstract: This dissertation work deals with the study of compressive strength behavior of Recycled Aggregate Concrete. Increase in population growth is leading to increase in various demands like cultivation, transportation, construction etc. Now a day’s, a tremendous increase in the demand for construction works like residential buildings, bridges, dams, roads etc. Because of this increase in demand, the availability in the sources of concrete ingredients is getting difficult. Hence people are looking for alternative sources for the concrete ingredients in order to fulfill their requirements. Crushing the concrete debris by suitable means, R.C.A and R.F.A can be removed from the parental concrete and after proper sieving, they can be made use in new construction work. In this ongoing project work it is concentrated only on use of R.C.A.. The main object in this investigation is to find out upto what percentage the N.C.A can be replaced by R.C.A in the concrete mix and to find out the extra quantity of cement to be added for each percentage replacement by R.C.A, to achieve its target mean strength.
