| Abstract: | 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. |

| Keywords: | layer steel fiber reinforced concrete freezing-thawing cycles durability |
