TEST ON MECHANICAL BEHAVIOR OF REINFORCED RECYCLED COARSE AGGREGTE CONCRETE BEAMS

摘要：

　　In order to reveal the mechanical behaviour of reinforced recycled coarse aggregate concrete beams,6 specimens were designed for test.The failure process and modes,loading-deformation and loading-strain curve were obtained from the experiment.Based on the test data,the influence of recycle aggregate replacement ratio and shear span ratio to the bearing capacity were analysed.The results showed that reinforced recycled aggregate coarse concrete beams failure pattern is similar to ordinary reinforced concrete beam,according to the shear spans difference,two type failure patterns were appeared,which are shear pressure failure and bending failure; shear span has obviously effect on the bearing capacity,yet the replacement only little effect.
