摘要
针对机场道面混凝土可能所处的环境,研究了不同养护条件下改性聚酯纤维混凝土和聚丙烯纤维混凝土的收缩变形性能,并对2种合成纤维混凝土的收缩变形性能进行了比较。结果表明,在各种养护条件下,掺入合成纤维均有利于减少混凝土的收缩,在相同掺量下,改性聚酯纤维的抗收缩性能优于聚丙烯纤维。
According to the real condition of pavement concrete in practice, the influences of different curing conditions on the shrinkage deformation of modified polyester fiber concrete and polypropylene fiber concrete were investigated and compared. The results show that synthetic fiber could reduce the shrinkage deformation of concrete within all curing conditions considered, while the adding dosage of fiber is equal,the shrinkage resistance property of modified polyester fiber is higher than that of polypropylene fiber.
