Abstract
A large amount of waste coconut shell is generated in India from temples and industries of coconut product and its disposal need to be addressed. Researchers have proposed to utilize it as ingredient of concrete. This experimental investigation was aimed to quantify the effects of replacing partially the conventional coarse aggregate by coconut shell to produce concrete. Concrete has become basic material in day to day life of humans. Low tensile strength and brittle nature are the basic defects in concrete. The present investigation is mainly focused on the effect of mechanical properties of concrete with coconut shell replacing coarse aggregate. In this investigation concrete having compressive strength M60 is used. Coconut shell is replaced in concrete from 0 to 40 % by weight.
