Experimental investigation on rice husk ash as cement replacement on concrete production
Highlights Use of rice husk ash as cement additive for sustainable development. Very fine RHA facilitates better pozzolanicity due to high specific surface area. 20wt% of fine RHA addition can produce acceptable strength of cement concrete.
Abstract The emission of CO2 has increased due to cement manufacturing and improper disposal of rice hush ash (RHA) leads to air pollution and land fill problem. To mitigate these issues, the RHA has been used as cement additive in concrete making. A Taguchi L27 fractional-factorial matrix was designed to assess the individual effects of key process variables like RHA loading, pozzolanicity, curing time, bulk density and RHA size. From the results, mechanical strength increased with decreasing RHA size and 20wt% RHA replacement is optimum for 15 and 60min grounded sample. The morphology of RHA are also discussed.
