摘　　要：通过普通混凝土、层布式钢纤维混凝土以及层布式混杂纤维混凝土在冻融循环下的相对动弹性模量、强度及质量变化的对比试验,研究了层布式钢纤维与聚丙烯纤维混杂应用对混凝土耐久性能的影响。结果表明,层布式混杂纤维的掺入,显著提高了混凝土的抗冻融耐久性能。In this present paper,the effects of the application of layer steel fibers and polypropylene fibers on durability of concrete were studied through the contrast experiments on the variation of the relative moving module and the mass of original concrete,layer steel fiber reinforced concrete and layer hybrid fiber reinforced concrete under freezing-thawing cycles condition.The test results indicated that the durability of freezing-thawing resistance of concrete will be improved remarkably by adding layer hybrid fiber.

关 键 词：层布式混杂纤维混凝土 冻融循环 耐久性
