Abstract: Increasingly, the landfill or open-air storage of waste concrete produced in the process of urban demolition and reconstruction will occupy a large amount of land resources and pollute the environment. Therefore, the recycling of waste concrete is the main measure to solve this problem. Through experiments, different proportions of recycled waste concrete coarse aggregates are used to replace natural limestone aggregates to prepare C40 concrete, so as to obtain the influence of different recycled coarse aggregate replacement rates on the working performance, mechanical properties and durability of C40 concrete. The results show that the replacement rate of recycled coarse aggregate is 40%, and the highest is not more than 60%.
