| Abstract: | The research and application of the frost resictence of recycled aggregate has great significance. The influences of the replacement rate of recycled coarse aggregate on the frost resitance 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 the in- crease of the replacement rate of the recycled fine aggregate. The relative dynamic modulus of recycled coarse the freeze-thawing circulation norm and meets frost resistance requirements. |
