This research work investigates the effect of Rice husk ash (RHA) when used as a partial replacement of ordinary
Portland cement in concrete and mortar sample. Before using RHA as a partial substituent of cement, EDX and XRD
analysis were conducted on RHA sample. Slump cone test was performed for various replacement level of cement i.e 0%,
10%, 15%, 20% with RHA on concrete. The test result showed reduction in workability as the percentage replacement of
Ordinary Portland cement (OPC) with Rice hush Ash (RHA) increased. Moreover, Compression tests results carried out on
mortar specimens showed reduction in strength with the increase in amount of RHA.
