Experimental Analysis of Natural Sand with Crushed Sand of M20 Concrete Mix

Abstract

Concrete itself as a mixture of water, cement, sand and aggregate in addition with admixtures.as the natural sources of aggregates are different the strength shows variation. There is shortage of natural sand due to heavy demand indifferent construction activities such as residential, commercial, bridges etc.it is very needful to find suitable substitute. The cost effective & simplest way to getting substitute to natural sand is by crushing natural stone to get manufactured sand i.e. M-sand of desired size & shape which would free from all deleterious materials. Now a day V.S.I. crusher is a cheapest machine for crushing stone in cubical shape & manufacture M-sand.in Maharashtra every city or town does not have V.S.I. crusher so artificial sand i.e. M-sand is not available at everywhere so we want to combine natural sand with artificial sand. For the purpose of testing concrete mixes are designed for M20 with 50% natural sand & 50% crushed sand and also all natural sand replaced by M-sand.to evaluate strength the compressive strength is taken on compressive testing machine.
