| Abstract: | In this paper,the frost resistance of recycled concrete with antifreeze and the effect on the quality when it was maintained in sub-zero temperature were discussed.Its mechanical capability was indicated by compressive strength.The compressive strength after being cured in standard condition for 28 days and the ability to resist the freezing-thawing cycles were studied as well.At last,comparison was made with the recycled concrete without any admixture. |
| Keywords: | antifreeze recycled concrete frost resistance freezing-thawing circle |
