Abstract

This study shows the results of experiments evaluating the use of palm kernel shell powder from palm oil refinery waste production as partial replacement for Ordinary Portland Cement. Many researchers have studied the use of agro-waste as constituents in concrete. The objective of this research is to identify the performance of palm kernel shell powder s a partial cement replacement in the production of concrete. Palm kernel shell powder various amounts, namely 5%,10%,15% and 20 % by volume was added as a replacement for Ordinary Portland Cement. The results showed that palm kernel shell powder concrete greatly improved the compressive and flexural strength of concrete. The rate of water absorption of palm kernel shell reduced as palm kernel shell filled up the existing voids while making it impermeable. However, the compressive strength of the palm kernel shell powder decreases gradually when the amount increased. It can be concluded that the optimum amount of palm kernel shell powder as partial cement replacement is 15%. In the correction, an experimental investigation of ultrasonic pulse velocity, carbonation test, flexural strength, and water absorption test was undertaken to palm kernel shell powder and admixtures as partial replacement cement in concrete.
