The Compressive and Flexural Strengths of Self Compacting Concrete SCC produced by the replacement of 100%Ordinary Portland Cement (OPC) with the Mix of Rice Husk Ash (RHA), Limestone (LS) and Ordinary Portland Cement (OPC) is the subject of this investigation. Concrete Specimens were produced with 0%RHA, 5%RHA,10%RHA, 15%RHA, 20%RHA,5%RHA1%LS, 10%RHA2%LS, 15%RHA5%LS, 20%RHA7%LS with the remaining percentage as Ordinary Portland cement (OPC), added with fine aggregates, coarse aggregates and water were cured for a period of 28 days. The cured specimens were subjected to compressive and flexural tests to determine their strengths. Optimum compressive and flexural strengths of 20.62N/mm2 and 6.43N/mm2 respectively were obtained for a Mix of 10%RHA2%LS88%OPC which was higher than the compressive strength of 19.56N/mm2 for100% OPC.
