Abstract:
Cement is widely noted to be the most expensive constituent of concrete. The entire construction industry is in search of a suitable and effective waste product that would considerably minimize the use of cements and ultimately reduce the construction cost. Rice husk ash (RHA) which has the pozzolanic properties is a way forward. This research study was therefore, experimentally carried out to determine the optimal amount of Ordinary Portland Cement (OPC) to be partially replaced with Rice Husk Ash (RHA) in concrete production. The rice husk ash was collected from Tilda Uganda limited and burnt at Uganda Clays Limited. Ordinary Portland cement (OPC) was replaced with Rice hush Ash (RHA) by weight at 0%, 5%, 10%, 15%, 20% and 25% with a mix design of 1:1.84:2.44. Chemical characterization tests were carried out on the rice husk ash to determine the major oxides of silica, alumina and iron. Physical tests carried out were slump test on fresh concrete and Compressive Strength test , flexural and splitting tensile strength tests on hardened concrete at different ages of 7, 14 and 28 days of curing. The results on chemical characterization tests revealed that the sum of the percentage of the three major oxides (SiO2,Fe2O3 and Al2O3) were greater than the set standard result (70%) while for the physical tests the slump test results decreased as the percentage replacement of Ordinary Portland cement (OPC) with Rice hush Ash (RHA) increased, which indicated less workable concrete. The compressive strength, flexural and splitting tensile strength tests of the hardened concrete also decreased with increasing Ordinary Portland cement (OPC) replacement with Rice Hush Ash (RHA).
