Mixture Proportioning Methodology for Concrete Containing Coconut Shell

Abstract

This research has considered crushed coconut shell and crushed granite as coarse aggregate for the production of concrete. Studies were carried out on the physical properties of crushed coconut shell and crushed granite. Thirty one random mixes were generated using a statistical software package known as Mini Tab 14. A total of 108 cubes were cast and cured for 28 days after which they were crushed under machine and their compressive strength determined. From the result obtained, models were developed using Mini Tab 14 of which direct comparism was made between the modal data and experimental data. The concrete cubes had a compressive strength ranging from 8.94N/mm2 – 27.11N/mm2
