Effects of different cyclic loading on lightweight self-compacting concrete

Abstract

Self-compacting concrete (SCC) use is increasing and understanding its behaviour under cyclic loading is therefore important. This research study investigated the behaviour of lightweight SCC under eight different types of compressive cyclic loading. Three loadings were applied to examine pre-peak lightweight SCC behaviour, two loadings were used to examine the post-peak behaviour and three loadings are complete. The total loading in the pre- and post-peak range exposed lightweight SCC to compressive were used to examine both pre- and post-peak stages. 120 standard cylindrical specimens were tested. 90 specimens were exposed to cyclic compressive loading and 30 specimens to uniform compressive loading. The mean compressive strength of the study specimens was 40 MPa and the slump flow was 64 cm. The results showed that increasing the number of loadings reduced the peak strength and increased strain. The reduction in strength and increase in strain depend on the number of pre-peak loadings. The damage caused by cyclic loading, the amount of energy absorbed due to the cracks caused by loading and the amount of energy absorbed by the concrete in hysteresis loops were studied with respect to the type of loading.
