| 摘 要： | 为找出满足混凝土不同抗冻性要求的最小水泥用量,设计了掺与不掺引气剂的混凝土各6组进行冻融循环试验.结果表明:在水胶比相同的情况下,随着水泥用量的增加,混凝土抗冻性能提高;粉煤灰及引气剂能明显改善混凝土的抗冻性能.针对不同情况,分别给出了混凝土中水泥用量最低值.

| Abstract: | To identify the minimum cement content with the different frost resistance of concrete,12 groups of concrete were prepared,that is,6 groups of concrete without air entraining admixture,and 6 groups of concrete with air entraining admixture.The freeze-thaw tests have been carried out.Test results show that at the same mw/mb,with the increase in cement content,frost resistance of concrete improves,fly ash can improve the frost resistance of concrete obviously,and air entraining admixture can improve the frost... |

| Keywords: | concrete frost resistance cement content water-binder ratio air entraining admixture fly ash |
