Comparative Study of Strength of M20 Grade of Concrete by Replacing Water with Starch Water

Abstract

There are many purpose we are using water every day  in our life and it is a daily need of our life .water is used as binding agent in concrete mix design and is important ingradient for mix design of concrete ,to save water we are replacing he water content in mix design by the rice starch water fully and partially and the potato starch water fully and partially and finding the strength and other properties of concrete like workability of concrete and the compressive strength of concrete mix design Of M20 Grade Concrete at 7 , 14 , & 21 Days  is 13 , 19.4 & 20.3 mpa respectively
