Influence of Hauling Time on Fresh Properties of Self-Consolidating Concrete

This study was intended to evaluate the influence of hauling time on fresh self-consolidating concretes (SCCs) made with slump flows of 508, 635, and 711 mm (20, 25, and 28 in.). Nine different hauling times—10, 20, 30, 40, 50, 60, 70, 80, and 90 minutes—were used. Fresh performance of the selected SCCs was affected by hauling time in the form of loss in flowability and gain in flow rate and dynamic stability. A remediation technique consisting of admixture overdosing was able to revert the adverse influence of hauling time on the fresh characteristics of the selected matrices, as it produced SCCs with similar flow characteristics, dynamic stability, and passing ability to those obtained at the reference hauling time.
