Study on Effects of Different Replacement Rate on Bending Behavior of Big Recycled Aggregate Self Compacting Concrete
Big recycled aggregate self compacting concrete is a new type of recycled concrete,which has the advantages of low hydration heat and green environmental protection,but its bending behavior can be affected by different replacement rate.Therefor,in this paper,the research status of big Recycled aggregate self compacting concrete was systematically introduced,and the effect of different replacement rate of big recycled aggregate on failure mode,crack distribution and bending strength of the beam were studied through the bending behavior test of 4 big recycled aggregate self compacting concrete beams.The results show that: The crack distribution of the beam can be affected by the replacement rate; The failure modes of big recycled aggregate beams are the same as those of ordinary concrete; The plane section assumption is applicable to the big recycled aggregate self compacting concrete beam; The higher the replacement rate,the lower the bending strength of big recycled aggregate self compacting concrete beams.
