Cube samples of size 150 x 150 x150 were prepared for concrete grade 30 and cured in water for 7, 14, 28, 90, 120 and 180 days after which they were subjected to compressive strength, tensile strength, durability, porosity, water absorption, slump, compact factor and shrinkage tests. The cassava peel ash was obtained by calcinations of cassava peel to c temperature. This paper investigated the effect of partial replacement of cassava peel ash with ordinary Portland cement at 5, 10, 15, 20 and 25%. The utilization of locally available materials such as cassava peel ash that can either reduce or replace the conventional ones is being considered.
