This project gives an account of the study conducted on the substitution of Palm Kernel Shell (PKS) for coarse aggregate in concrete works. It is aimed at determining the properties of PKS that makes it suitable as a replacement for natural aggregate in concrete works and the effects of mixing ratios of Palm Kernel Shell Concrete (PKSC). A number of tests were conducted on the PKS and concrete produced with palm PKS. Tests conducted on PKS were specific gravity and water absorption capacity. The results obtained gave the specific gravity and water absorption capacity of PKS as 1.37 and 10% respectively, thickness ranging from 1.0–3.0 mm, size ranging from 2–15 mm. While the tests conducted on PKSC include, density, compressive strength test, splitting tensile strength test and flexural strength, concrete mixes of 1: 2.48: 1.68 were used to produce cubes, cylinders and beams which were cured for 28 days before testing. Normal coarse aggregates was replaced in concrete in such gradation 0%, 10%, 20%, 30% and % 40%. The density of the PKSC is lower which characterize PKSC as a Light Weight Concrete (LWC). The compressive strength and split tensile strength test results showed that 30% of PKS replacement is optimum. The flexural strength of PKS reinforced concrete beam was closer to conventional reinforced concrete beams. 1% of hooked end steel fibre was added to 30% of PKS replacement concrete to improve the split tensile strength and flexural strength. The density test, compressive strength test, split tensile strength and flexural strength were conducted for PKSC with steel fibre. The test results show that steel fibre increases the compressive strength, split tensile strength and flexural strength of PKSC.
