In this study, punching shear of slabs and the flexural and shear behaviour of reinforced concrete beams were investigated in connection to the type of concrete (self compacting concrete (SCC) and normal concrete (NC)), and compressive strength (40 MPa). To achieve these objectives, two beam have been furnished, tested, and reviewed. First, one consists of SCC beam and the second one consists of NC beam. We are add admixtures like fly ash and GGBS. According to test results, for beams that failed in flexure, SCC beams showed a similar ultimate load to NC beams. When it came to slender beams collapsing in shear, NC beams showed a 6.75% higher ultimate load than SCC beams for beams , whereas beams with fc' 40 MPa showed nearly the same ultimate load value. The final loads for SCC and NC beams for beams did not differ noticeably. It was discovered that SCC slabs displayed a 17.25% higher ultimate punching shear load than NC slabs for the six geometrically similar slabs (three slabs made with SCC and three slabs made with NC of various concrete strengths) thatwere intended to fail in punching shear.
