This study investigates the influence of fly ash substitution for Ordinary Portland Cement (OPC) on the compressive and splitting tensile strengths of Self-Compacting Concrete (SCC) mixes. The findings reveal that while early age strength may decrease with fly ash substitution, strategic material selection, such as incorporating foundry sand, mitigates this decline. Satisfactory fresh properties were achieved across SCC mixes labeled SCC1-SCC4, with compressive strengths ranging from 30.49 to 19.19 MPa at 28 days. Additionally, the study demonstrates the feasibility of producing SCC with adequate strength at elevated temperatures, with compressive strengths ranging from 39.48 to 29.03 MPa at 91 days. Higher fly ash replacements result in SCC mixes suitable for reinforced concrete construction, with compressive strengths increasing with age. Economical SCC production is viable with up to 50% OPC replacement with fly ash. Moreover, splitting tensile strengths exhibited a consistent decrease with temperature and an increase with aging, indicating the material's long-term performance. These findings provide valuable insights for optimizing SCC production processes and material selection to meet diverse application requirements.
