Abstract
In this study, the effect of maize cob ash (MCA) as a supplementary cementitious material on the mechanical properties of concrete was evaluated. Maize cob ash as a pozzolanic material was partially used to replace cement ranging from 0% to 20% by weight in increment of 5% with varying water-cementitious ratios of 0.44 and 0.56. The results of this study indicated that the strength of concrete decreased as the amount of maize cob ash in the concrete mix increased. Generally, it can be concluded that maize cob ash can be utilised as partial replacement for cement in concrete at a suitable amount and can be used for building walls and other minor construction works. It was also established in the study that the optimum amount of 6.43% maize cob ash cement replacement could be used for structural members with compressive strength of 25 MPa.
