Research on Application of RCA in Cement Concrete

FU Gong-fun,ZHAO Wen-qin et al

  Abstract : Based on the current specifications for communications, technical indexes of recycled concrete aggregate (RCA) are analyzed and tested through indoor examination. The performance of new cement concrete made from recycled concrete aggregate is also comprehensively studied. Compared with conventional cement concrete, the feasibility of recycling of waste cement concrete pavement slab is discussed finally。
