This research is aimed at investigating the effect of using plantain peel ash (PPA) obtained from plantain peel as a partial replacement of ordinary Portland cement (OPC) on the mechanical properties of concrete. The PPA used in this research work was subjected to control burning of Plantain peel into ash, which was grinded and passed through 75µmm BS sieve. PPA was used in partial replacement of ordinary Portland cement in the following percentages 5%, 10%, 15%, 20%, and 25%.These partial replacement was used to produce concrete. PPA was found to contain all major chemical constituent found in cement with the exception of Gypsum,CaSO4, which are SiO2 (12.249), Fe2O3 (3.988), Al2O (2.653), CaO (7.897) and loss on ignition (LOI) was not found and it also contains other minor oxides found in cement. Consistency of cement-PPA paste was found to increase with increase in PPA content. Likewise the Setting time and Soundness of cement-PPA paste also increase with increase with PPA content. The cement-PPA and Compressive strengths were found to increase with curing time and decrease with cement replacement by PPA. It was observed that 10% replacement of cement with PPA attained the highest strength for all the curing ages.
