| Abstract: | The recycled aggregate surface is wrapped with a layer of hardened cement mortar,which leads to a complicated strength change of recycled concrete.With the water absorption capacity of the aggregate as an index,this paper discusses the calculation of mortar content with water absorption capacity and replacement rate,and the influence of recycled aggregate with different mortar contents on concrete 7 d,28 d strength,and the linear relationship between recycled concrete strength and cement-water ratio,as well as relevant working performance. |

| Keywords: | recycled aggregate mortar content recycled concrete strength linear relationship working performance |
