Abstract
The huge quantity of concrete is consumed by construction industry all over the world. In India, the conventional concrete is produced using natural sand from river beds as fine aggregate. Decreasing natural resources poses the environment problem and hence government restriction on sand quarrying resulted in scarcity and significant increase in its cost. This paper presents the optimization of partial replacement of manufactured sand by natural sand in High Performance Concrete. Concrete mixes were evaluated for durability properties of manufactured sand in concrete by partially replaced with natural sand with by three proportions ( ie 25%,50%,75%). In this study, Chloride ion penetration and Water absorption calculated for M60 grade concrete with manufactured sand.
