Waste Coconut Shell as a Partial Replacement of Coarse Aggregate in Concrete Mix - An Experimental Study

In construction industry the rising cost of construction material is the great factor. The prices of building materials are rising day by day. Therefore this is a most priority of all human being to encourage or research on sustainable material which will help to use such waste material as construction material with less cost and safety of structure. The course aggregate is the main constituent of concrete mix, hence in this paper we used coconut shell as a coarse aggregate has been discussed based on the results obtained from test results. The use of coconut shell can also help the prevention of the environment. The paper aims at analyzing compressive strength of concrete (M20-11.53) produced using coconut shell as substitute for conventional coarse aggregate with 0 %, 25 %, 50 %, 100 % partial replacement. Three sample cubes are prepared for M20 grade concrete mix for each case another aim of this paper is to spread awareness about use of coconut shell as construction material in civil engineering.
