Abstract
This paper summarizes the research work on the
properties of Rice Husk Ash (RHA) when used as partial
replacement for Ordinary Portland Cement (OPC) in concrete. OPC
was replaced with RHA by weight at 5%, 10% and 15%. 0%
replacement served as the control. Compressive Strength test was
carried out on hardened 150mm concrete cubes after at1, 3, 7, 28, 45
& 56 days curing in water. The results revealed that the Compacting
factor decreased as the percentage replacement of OPC with RHA
increased. The compressive strength of the hardened concrete also
decreased with increasing OPC replacement with RHA. It is
recommended that further studies be carried out to gather more facts
about the suitability of partial replacement of OPC with RHA in
concrete.
