Abstract

Philippines was the 2nd largest producer of coconut in the world. This massive production of coconut corresponds to a large amount of coconut agricultural waste and the utilization rate of these were insufficient to cover the agricultural waste production of coconut shell. Hence the study of incorporating coconut shell as coarse aggregate was conducted. The compressive strengths, workability, and density classification of concrete, with Coconut Shell Aggregate (CSA) as coarse aggregate, was studied with varying partial volume replacements: 0%, 10%, 20%, 30%, 40%, and 50%. A mix proportion of 1: 1.6 :0.7 was used as a base mix proportion for the control sample group (0%). A constant water to cement of 0.5. Tests were carried out to determine the compressive strength, density, and workability of the concrete. Together, eighteen samples were tested. It was observed at 10% volume replacement yields compressive strength containing coconut shell as coarse aggregate that passes the minimum compressive strength requirement for ACI lightweight concrete.
