Abstract:

This study investigated the effect of palm kernel shell ash (PKSA) as a partial replacement for ordinary Portland cement in high strength palm kernel shell ash concrete. The mix design targeted a compressive strength of 50MPa at 28days. The properties studied include workability of fresh concrete, compressive strength, flexural tensile strength and splitting tensile strength hardened concrete. PKSA contents in mixes ranged between 0% and 50% by weight of cement The use of palm kernel shell ash (PKSA) has advantages like; reduction in cost of concrete, solving environmental pollution problems as well as reduced the number of landfill areas required for disposing the PKSA. PKSA partial replacement for cement not only reduced the strength properties but also the workability of steel fibre reinforced concrete. Also it was observed that increase in percentage of PKSA led to a corresponding reduction in both flexural and compressive strength when compared with control concrete. Since the strength reduced with further addition of PKSA from 25%, it is recommended that optimum replacement level of ordinary Portland cement by Palm kernel shell ash is 25% for good compressive and tensile properties.
