Commonly, Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete which release large amount of carbon dioxide while manufacturing. Consequently there is important to utilize choice to limit the effect on climate. In this paper Rice husk debris were to some degree traded for concrete material. In this investigation ice husk debris are utilized as a swap for concrete in different extents, for example, 0%, 7.5%, 10%, 12.5%, 15%, 20%.Then prepared M20 concrete treated with both acidic and non-acidic medium by using rebound hammer test to calculate the strength of concrete. As non-destructive test carried out to study the variation in strength of concrete with or without rice husk ash. As it is observed that replacing the cement with 10% & 12.5% RHA give the higher compressive strength.
