Experimental Study on use of Crushed Rock Powder as Partial Replacement for Fine Aggregate in Concrete

Concrete is commonly used building material, and it is extensively used, hence this project is aimed to reduce the use of natural sand by using crushed rock powder(CRP) as a replacement for fine aggregate in concrete .Thereby reducing the exhaustion on natural sand. The project involves the process in which fine aggregate in concrete is replaced by CRP at 0%, 20%, 40% and 60% replacement. Grade of concrete M25 is selected for the project. The project includes determination of compressive strength and split tensile strength at the ages of 7 days and 28 days. The strength properties of concrete with CRP replacement are compared with that of Normal Concrete (NC) which does not contain CRP.
