Abstract

The results of a study dealing with the influence of temperature on the fresh performance of self-consolidating concretes (SCC) made with slump flow of 508, 635 and 711 mm are presented. Seven different temperatures, namely: 43, 36, 28, 21, 14, 7, and −0.5 °C, to simulate hot and cold temperatures were used to evaluate the unconfined workability, the rate of flow ability or viscosity per inference, and the dynamic stability of the trial matrices. The fresh performance of SCC was significantly affected by hot temperatures (i.e. 43, 36, and 28 °C) and marginally influenced by cold temperatures (14, 7, and −0.5 °C). The remediation method by way of admixture overdosing was successful to reverse the change in fresh properties of the self-consolidating concretes in elevated temperatures. The selected matrices did not require any remediation in cold temperatures.
