| Abstract: | The research and application of recycled concrete are of great significance for environmental protection and its durability is an important index of production and application.The influences of the replacement rate of recycled coarse aggregate,mineral admixture and other factors on the frost resistance of recycled concrete are studied in this paper.The experimental results show that the mass loss rate of recycled coarse aggregate concrete meets the experimental requirement by 5% and it descends along with t... |
| Keywords: | recycled coarse aggregate mineral admixture frost resistance |
