Abstract:
This paper deals with study of impact of cooling regimes on the mechanical properties of Self-Compacting Concrete (SCC), exposed to elevated temperatures. Compressive and split tensile strengths of SCC50 at ages of 7 and 28 days are studied after one and half hour exposure to temperatures ranging from 100oC to 500oC. The specimens are tested in hot condition as well as in cooled condition i.e., they are cooled down to room temperature by air cooling and water quenching. The comparison revealed that water quenched specimens exhibited lower residual strengths than air cooled specimens and hot state specimens.
