An experimental investigation on the use of palm oil shell (PKS) as partial replacement by wt. % of crushed aggregate has been evaluated. A mix ratio of 1: 1.5: 3 with a cement content of 382 kg/m3, and water-cement (w/c) ratio of 0.55, was used for concrete specimen. Four concrete mixes labeled M-00 to M-30, at replacement intervals of 10 %, were used to fabricate concrete specimens that were cured above the conventional age of 28 days (i.e. up to 90 days), before testing. The microstructure results showed that PKS used had acceptable qualities within the specified limits of lightweight aggregate, and both the workability and compressive strength of the PKS-concrete decreased as the percentage replacement was increased. It was observed that curing above the conventional age of 28 days, additional improved the strength of the concrete specimens. The optimum replacement level was at 10 %., and a linear regression model that was significant with good correlations of the statistical data was developed.
