摘要
利用RILEM推荐的混凝土抗冻性能试验标准(CDF)研究了粉煤灰陶粒混凝土与普通混凝土的抗盐冻性能。结果表明:相同强度等级的掺加矿物掺合料的粉煤灰陶粒混凝土的单面抗冻性大大优于普通混凝土的单面抗冻性;矿物掺合料的56次的耐单面抗冻顺序是:硅灰+矿渣>硅灰+粉煤灰>矿渣+粉煤灰>硅灰>粉煤灰>矿渣。
The RILEM recommended test method（CDF）about frost resistance of concrete was adopted to do a comparative study on frost resis-tance of fly ash ceramsite concrete and that of ordinary concrete.The results indicate that the single surface＇s frost resistance of fly ash ceramsite con-crete with mineral admixture is much better than normal density concrete＇s.And the rank of the single surface＇s frost resistance at 56 cycles of fly ash ceramsite concrete with different mineral admixture is：silica fume and slagsilica fume and fly ashslag and fly ashsilica fumefly ashslag.
