Thermal Treatment of Self-Compacting Concrete in Cast-In Situ Construction

Abstract:

Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. Thermal treatment (TT) of SCC can significantly accelerate the strength growth during cast-in-situ construction. This paper presents a technology of TT of structures for cast-in-situ construction with SCC. Application of this technology allows to reduce the turnover of formwork, the labor costs for construction, and the construction period. We also studied the issue of strength development of SCC during TT. For our study, we used SCC of grade C25. Test samples were cured with TT by infrared radiators for 7, 9, 11, 13, 16 and 24 hours. Then warmed samples were tested for compressive strength after 0.5, 4, 12 and 24 hours of cooling period. Study was carried out on the basis of analyzing, generalizing and evaluations of experimental data. A mathematical model is proposed for determining the compressive strength of SCC after one day of curing of SCC with TT.
