Assessment of Palm Kernel Shell Powder Strengthened with Renolith as Partial Replacement for Cement

Abstract

The increase in the population density of the world today requires man to find a suitable substitute to cement as a major material used in construction in order to find an economical, safe and eco-friendly structure for habitation. Palm Kernel shells contribute to the ever-growing volume of solid waste in the environment and its conversion to a viable construction material cannot be overemphasized. This research is therefore focused on the use of Palm Kernel Shell Powder (PKSP) as a partial replacement for cement. Experimental tests were carried out on the PKSP at replacement levels of 0,10, 15, 25, 50 and 75%. Renolith, a chemical polymer was added at 0, 12.5 and 25% by volume to the concrete mix. Slump and compressive strength tests were carried out in line with relevant specifications. The results revealed that PKSP can adequately replace cement at an optimum value of 15%. The addition of Renolith at 12.5% to the mix also improved the strength and workability properties of the mix. It was concluded that the use of PKSP as partial replacement for cement will provide an economy of 15% by volume for cement and an eco-friendly environment through the conversion of PKS wastes to construction material.
