In concrete by adding different content of corn stalk fiber and tire just silk fiber,corn straw stalk fiber and waste tires are analyzed of steel fiber content on concrete 7 d and 28 d cube compressive strength,the influence of and the frost resistance test.The results show that,under the appropriate fiber content,corn straw fiber and tire wire fiber can improve the 7-day and 28-day cubic compressive strength of concrete.The optimal group is 0.6%corn straw fiber and 1.0%tire wire fiber,and the compressive strength is 8.78%and 15.92%higher than that of the reference group respectively.The addition of two kinds of fibers also improved the freezing resistance of concrete,and the loss rate of the optimal group was 3.63%,4.46%and 7.31%lower than that of the benchmark group at 25,50 and 75 freeze-thaw cycles,respectively.
