Abstract: This paper assesses the suitability of using sugarcane bagasse ash (SCBA) as partial replacement of cement in concrete as well as the effect of its grinding on the mechanical properties of concrete. The SCBA was ground in a ball mill for 60 minutes and 30 minutes and its physical and chemical properties determined to establish if it was pozzolanic. 0%, 10%, and 20% by weight of cement was then replaced by the ash in concrete and the physical properties of concrete determined.
