Concrete is a construction material composed of cement, fine aggregates and coarse aggregates mixed with water which hardens with time and has a compressive strength and flexural strength.This project was conducted on aggregates and cement is replaced by Rice Husk Ash and Metakaolin. The purpose of this experimental is to increase mechanical properties of concrete; when cement is partially replaced with RHA and Metakaolin. Metakaolin is obtained from industrial wastes. Metakaolin is the anhydrous calcined form of the clay mineral kaolinite .As Metakaolin is cost effective, fine and pozzolanic in nature it can be used a substituent for cement material. Rice husk ash is an abundantly available and renewable agriculture by-product from rice milling and it contains about 30%–50% of organic carbon. By using rice husk ash it gives future strength to the structures. The mix proportion of the concrete is adopted as 1:1.5:3 for the M20 grade concrete.
