Experimental study of concrete by effective utilization of agro-waste and metakaolin as a partial replacement for cement
Use of metakaolin (MK) as a partial substitute for cement is studied with agro-waste materials of rice husk ash (RHA) and sugarcane bagasse ash (SBA) to target up to M50 concrete grade in normal and acidic curing environments. Experimental work and ANOVA analysis indicate that 30% partial replacement of cement by SBA 15%, MK 5% and RHA 10% is the optimum combination; achieving the highest mechanical strengths for tested grades of concrete. Strength improvements are noted at 10% and 20% under normal and acidic curing respectively; while chloride penetration and permeability are reduced. Noteworthy, the combination is achieving a high strength of more than 61 MPa (28 days) even in acidic curing that is closer to M60 concrete grade.
