dc.description.abstract Self-Compacting Concrete (SCC) is a concrete which can be placed under its own weight without vibration. Whereas Vibrated Concrete (VC) is a concrete which is compacted by means of mechanical vibration. SCC exceeds the current limitations of VC in providing superior material properties, namely passing ability through dense reinforcement resulting in fewer material defects and increasing durability. SCC can be considered as a feasible option where limitations of VC in relation to achieving full compaction of congested reinforcement structural elements. This paper compares the structural performance of congested reinforcement beams cast with Self Compacting Concrete (SCC) and identical beams cast with Vibrated Concrete (VC). Two different geometric cross-section and length, different longitudinal reinforcement ratios, and same stirrup configuration for all specimens were used. A total of 12 beams: 6 were tested in the experimental investigation (4 were cast with SCC and 2 were cast with VC in reinforced sections) and 6 (3 for each type of concrete) were investigated using software simulation. The results were compared with design performance prediction as per Euro code2. All beam specimens were tested under monotonic mid-span concentrated loading to determine the overall structural behavior of reinforced concrete beams. The test results on reinforced beams showed that SCC concrete performed better in reinforcement congested beam element than the referenced VC concrete beam element. The study also showed that the difference in mix composition of SCC from that of VC concrete would have no effects on the overall load-deflection response of reinforced concrete (RC) beam. en_US
