Strength Development of Fine Grained Mortar Containing Palm Oil Fuel Ash as a Partial Cement Replacement

This study was focusing on the utilization of Palm Oil Fuel Ash (POFA) and the effect of fine sand to develop the strength of the mortar. The flexural and compressive strength of fine grained mortar (FGM) with the addition of POFA and the sand usage with a size less than 1 mm were investigated. Then, the optimum percentage of POFA as a replacement material for cement was determined. Cement was partially replaced with POFA at various percentage...
