摘　　要：设计4种混凝土,即基准混凝土、钢纤维增强混凝土、耐碱玻璃纤维增强混凝土及聚丙烯纤维增强混凝土,以此4种混凝土为研究对象,进行混凝土抗冻性试验。试验结果表明:纤维增强混凝土的抗冻性能好于基准混凝土的抗冻性能;本试验的3种纤维增强混凝土中,抗冻性能最好的是聚丙烯纤维增强混凝土,其次是耐碱玻璃纤维增强混凝土,再次是钢纤维增强混凝土。There are 4 groups of concrete,that is,control concrete,steel fiber reinforced concrete,alkali-resistant glass fiber reinforced concrete,and polypropylene fiber reinforced concrete.For the 4 groups of concrete,freezing and thawing tests are carried out.Test results show that the frost resistance of fiber reinforced concretes in the test is all better than that of control concrete,and among the the fiber reinforced concretes in the test,frost resistance of polypropylene fiber reinforced concrete is the best,frost resistance of alkali-resistant glass fiber reinforced concrete is the second,and frost resistance of steel fiber reinforced concrete is the third.
