Abstract
Climate changes have been an issue to consider in the last few years. The
average global temperature has increased at the fastest rate in recorded history and this trend is accelerating. These statistics motivated the current work to
explore SCC production in hot weather. In this research, the performance of selfcompacting 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 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 test outputs were the most improved due to cooling SCC materials. 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 percentages.
