| Abstract | ||||
| Climate changes have been an issue to consider in the last few years. In this research, the performance of self-compacting concrete in simulated hot weather conditions is investigated. Test parameters included the ambient temperature, induced materials temperature, and the use of a retarder. The rheological properties, early shrinkage, and compressive strength were determined for different test parameters. The performance enhancement due to cooling the concrete materials and the use of a retarder was assessed and quantified. The results showed that the use of a retarder had an adverse effect on the compressive strength between 7 and 90 days in simulated hot weather conditions. The J-ring outputs were the most improved due to cooling SCC materials. On the other hand, V-funnel time T5 and the 28-day compressive and tensile strength were the least improved. The use of a retarder further reduced the compressive and tensile strength improvement percentage and increased the percentage enhancement of V-funnel T5 time. | ||||
