Comparative Study on Cost Analysis of Natural & Manufacture Sand in Residential Building

Abstract

The huge quantity of concrete is consumed by construction industry all over the world. In India, the conventional concrete is produced by using natural sand obtained from riverbeds as fine aggregate. The cheapest and the easiest way of getting substitute for natural sand is by crushing natural stone to get manufactured sand which would be free from all impurities. Manufactured sand is a term used for aggregate materials less than 4.75mm and which are processed from crushed rock or gravel. The concrete mixes having different mix proportions for both natural and manufactured sand (i.e. 100%NS+0%MS, 70%NS+30%MS, 40%NS+60%MS, and 0%Ns+100%MS) were prepared for M30 grade of concrete for cubes. Then there were 2 case studies is taken in which slab concrete cost of building by done construction and concrete cost of same quantity by my trial mix variation is compared. And this cost comparison of trial mix is done with cost of Natural sand & Manufactured Sand obtained from 3 different cities
