Abstract: Self-compacting concrete (SCC) has found wide applications in civil engineering structures, because it has the merits of high filling ability and good anti-segregation before hardening while good mechanical properties after hardening. However, the requirements of high volume binder and sand-to-aggregate ratio in self-compacting concrete may lead to reductions in the modulus of the SCC as well as the anchoring strength between the concrete and steel bars. If the mixture of self-compacting concrete is not reasonably optimized, the mechanical properties of self-compacting concrete structure may not be satisfying. So, it is important to investigate the flexural behavior of reinforced self-compacting concrete and normal concrete (NC) beams. In order to study the bending and shearing behavior of self-compacting concrete beam, an experimental program, which consists of eight self-compacting concrete beams and four corresponding normal concrete beams, is conducted to investigate their cracking loads, flexural capacities, shear capacities and failure modes. Comparisons of the flexural behavior between the self-compacting concrete members and normal concrete members are made and conclusions are come to. The testing results provide references for the design of self-compacting concrete structures and establishing related code provisions.
