Compressive Strength of Concrete by Using Coconut Shell

Abstract

The high cost of conventional construction materials is a dominating factor affecting housing system around the world. This has necessitated research work into alternative materials in the construction field. Conventional coarse aggregate namely gravel and fine aggregate is sand in concrete will be used as control. While natural material is coconut shell as course aggregate will be investigate to replace the aggregate in concrete. In this study, three different concrete mixes namely M20, M35 & M50 grade with different combination of natural material CS content in the proportion 0%, 10%, 20%, 30% and 40% will be replaced. Six sample specimen will be prepared for each concrete mixes. The parameters will be tested are compressive strength behaviour of cube specimens for 7 & 28 days. The main objective is to encourage the use of these "seemingly" waste products as construction materials in low-cost housing. It is also expected to serve the purpose of encouraging housing developers in investing these materials in house construction.
