摘    要:通过混合骨料混凝土的快速冻融循环试验,研究了浮石替代率、聚丙烯纤维、冻融循环次数对混合骨料混凝土抗冻性能的影响.结果表明:相对动弹性模量随着浮石替代率增加而增加;对于一定范围浮石替代率的混凝土,聚丙烯纤维的掺入能够改善混凝土的抗冻性能,浮石替代率为30%,聚丙烯纤维掺量为0.9 kg/m3的混合骨料混凝土,质量损失最小...

关 键 词:混合骨料混凝土  浮石  聚丙烯纤维  抗冻性能

Abstract:Through the fast freeze-thaw cycle tests of mixed aggregate concrete,the effect of pumice replacement rate,polypropylene fibers and freeze-thaw cycle time on the frost resistance properties of mixed aggregate concrete was investigated.The results show that the relative dynamic elastic modulus increase with the increase of the pumice replacement rate,and the introduction of the polypropylene fibers could improve the frost resistance of the concrete to a certain scope of the pumice replacement rate.As for thi...
Keywords:mixed aggregate concrete  pumice  polypropylene fiber  frost resistance
