Experimental Investigation on Compressive Strength Of M30 And M40 Grade Of Concrete With Partial Replacement Of Natural Sand by Robo Sand And Cement By Flyash

Abstract

Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Concrete plays a vital role in development of infrastructure i.e; buildings, industrial structures, bridges and highways etc. sand is basic material in concrete making that is required in large quantities But in the present scenario it is necessary to find the suitable substitute for sand, easy to produce and has all the required qualities for use in concrete. Manufactured sand is one among such materials to replace river sand, which can be used as an alternative fine aggregate in mortars and concretes.
