Analyzing Strength Properties of Self-Compacting Concrete at Elevated Temperatures
Abstract: 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 …
