Abstract

The use of Acha husk ash (AHA), Bambara groundnut husk ash (BGHA), Bone powder ash (BPA), Groundnut husk ash (GHA), Rice husk ash (RHA), and Wood ash (WA) to partially replace cement as a binder was reviewed. Analysis of results, using oxide composition, compound composition obtained using Bogue’s model, and results of test conducted in the laboratory, showed that only the replacement of cement with 10%BPA  exhibited a convincing increase in compressive strength of 7.14% above that obtain with the use of cement. Decrease in compressive strength observed with other agro waste was attributed to increase in SiO2 component and decrease in CaO component of cement-agro wastes mixtures. Incorporation of lime into the mixture is here by recommended for increase in strength.
