| Abstract | We evaluated self-compacting concrete mixtures containing various weight ratios of treated rice husk ash (RHA) obtained from electric power plant combustion. Ordinary or Type 1 Portland cement (OPC) was partially replaced by rice husk ash at levels of 0, 20, 40, and 60% of the total weight of binder materials (OPC and RHA). The binder material content for all mixtures was maintained at 525 kg/m 3 . Fresh and hardened state properties were tested including unit weight, slump flow J-ring, V-funnel flowing time and compressive strength. The rice husk ash consisted of partially amorphous silicon dioxide (SiO 2 ) particles with an equivalent volume mean particle size of 24.32 µm. Increasing the rice husk ash fraction resulted in a decrease in unit weight and an increase in the corresponding T 50 V-funnel times. A 40% rice husk ash replacement level in ordinary Portland cement can potentially develop the highest compressive strength, up to 440 kg/cm 2 . |
