Abstract: We investigated self-compacting concrete (SCC) mixtures containing rice husk ash (RHA) from electric power plants. Type 1 Portland cement (OPC) was partially replaced by RHA at levels of 0%, 10%, 20%, or 40% of the total weight of the binder materials (OPC or RHA, 275, 325, or 375 kg/m³). The mixtures were adjusted to maintain slump flow diameters of 50 ± 2.5 or 60 ± 2.5 cm. The RHA was in the form of partially amorphous silicon dioxide (SiO₂) particles with an equivalent volume mean particle size of 24.32 µm. Increasing the RHA fraction resulted in a decrease in unit weight and an increase in the corresponding water/binder ratio and T₅₀ V-funnel times. Use of 20% RHA produced a material with a long-term compressive strength similar to the control SCC.
