摘　　要：对普通混凝土、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进行了抗碳化试验.试验结果表明:纤维增强混凝土的抗碳化性能优于普通混凝土;3种纤维增强混凝土中,抗碳化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.The carbonation test of a plain concrete and 3 kinds of fiber reinforced concretes i.e. steel fiber reinforced concrete, alkali-resistant glass fiber reinforced concrete, and polypropylene fiber reinforced concrete were carried out. Test results show that the carbonation resistance of fiber reinforced concretes in the test is all better than that of control concrete, and among the fiber reinforced concretes in the test, carbon- ation resistance of polypropylene fiber reinforced concrete is the best, carbonation resistance of alkali-resistant glass fiber reinforced concrete is better than that of steel fiber reinforced concrete.

关 键 词：纤维增强混凝土 抗碳化 碳化深度
