Self-consolidating concrete (SCC) is a stable and cohesive high consistency concrete mix with enhanced filling ability\nproperties that reduce the need for mechanical compaction. Limited standards and specifications have been reported in the\nliterature on the structural behavior of reinforced self-compacting concrete elements. The significance of the research presented in\nthis paper stems from the need to investigate the effect of enhanced fluidity of SCC on the structural behavior of high strength selfconsolidating\nreinforced concrete beams. To meet the objectives of this research, twelve reinforced concrete beams were prepared\nwith two different generations of superplasticizers and designed to exhibit flexure, shear, or bond splitting failure. The compared\nbeams were identical except for the type of superplasticizer being used (second generation sulphonated-based superplasticizer or\nthird generation polycarboxylate-based superplasticizer). The outcomes of the experimental work revealed comparable resistance\nof beam specimens made with self-compacting (SCC) and conventional vibrated concrete (VC). The dissimilarities in the\nexperimental values between the SCC and the control VC beams were not major, leading to the conclusion that the high flowability\nof SCC has little effect on the flexural, shear and bond strengths of concrete members.
