Compressive test was carried out by applying a constant uniform
pressure through the testing machine on the cubes of the concrete blocks until failure occurs. Results show that
the more Rice Husk Ash used in the concrete mix, the lighter the finished concrete becomes, the higher the days
of setting of the concrete, the more the compressive force needed to break the block, also, the higher the
replacement level of the Rice Husk Ash up to 30 %, the stronger the block. The significance of the study is that
RHA therefore provides a positive effect on the mechanical strength of concrete mix, up to 30 % Rice Husk Ash
replacement up to the age of about 28 days and reduction in utilization of cement, and expenditures. Further
experiment should be performed to test the mechanical strength of concrete mix, beyond 30 % Rice Husk Ash
replacement above the age of about 28 days.
