Abstract


The paper discusses the effects of using different pozzolonic materials as a partial cement replacement material in mortar mixes. An experimental study of mortar made with Ordinary Portland cement (OPC) and 12% of OPC, replaced by different pozzolanic materials such as Fly Ash, Rice Husk ash, Silica Fume, Calcined Clay (Grog) and Slag (GGBS) were tested for the strength and durability properties, to determine the effect of these materials on mortar properties and was compared to control mortar mix. Mortar specimens were tested for compressive strength at age of 3, 7 and 28 days and flexural strength at age of 28 days. To investigate the mortar for its durability, the specimens after initial curing of 28 days were immersed in fresh water with solutions of 10% sodium sulfate (Na2SO4) and 10% magnesium sulfate (MgSO4) for another period of 3 months. Through this period, the specimens were tested for compressive strength at 60, 90 and 120 days to evaluate its durability.
