Experimental Study on Flexural Resistance of Reinforced Recycled-Concrete Beams

Abstract:

Seven reinforced recycled-concrete beams were tested to study their flexural resistance considering the variations of the strength of recycled-concrete and the reinforcement ratio of longitudinal tensile rebar. The aggregates of recycled-concrete comprised the machine-made sand and the recycled coarse aggregate. The failure state of normal section and the flexural resistance of reinforced recycled-concrete beams affected by the strength of recycled-concrete and the reinforcement ratio were discussed. The results show that the failure states of reinforced recycled-concrete beams were similar with those of the ordinary reinforced concrete beams. The flexural resistance was controlled by the reinforcement ratio, and influenced increasingly by the strength of recycled-concrete with the increase of reinforcement ratio. The failure resistance of reinforced recycled-concrete beam can be calculated by the method for ordinary reinforced concrete beam specified in current design code GB50010-2010.
