Research on reinforcement methods of recycled aggregate concrete

摘要

Due to the small apparent density, high bulk density, large porosity, high water absorption, high crush index value of recycled aggregate, the strength and working performance of concrete which is made of recycled aggregate is not as good as the original concrete. In allusion to the low strength and poor working performance of recycled concrete, in view of the reinforcement methods and pro-processing measures of recycled aggregate, the methods and techniques of strengthening recycled concrete are analyzed, techniques of recycled aggregate reinforcement are presented, then problems which need further research are proposed, which provides reference to the research and application of recycled concrete in reinforcement techniques.
