摘要：This paper discusses the effects of using different pozzolonic materials as a partial cement replacementmaterial in mortar mixes. An experimental study of mortar made with 43 grade Ordinary Portland Cement(OPC) and 12% of OPC partially replaced by different cement replacement materials (CRMs) such as flyash, rice husk ash, silica fumes, Calcined Clay (Grog) and Slag (GGBS) in mortar mixes. The mechanicalproperties of mortar mixes with these (CRMs) were tested to determine the effect of incorporating thesemineral admixtures on mortar properties and compared with that of control mix.Mortar specimens were cured in water for 28 days, through which, flexural strength and compressivestrength were tested at ages 3, 7 and 28 days. Then, the rest of specimens were immersed in fresh water withsolutions of 10% sodium sulfate (Na2SO4) and 10% magnesium sulfate (MgSO4) for period of 3 months.The specimens were also tested for variation in compressive strength at 28, 60 and 90 days to investigate thedurability properties.
