材料性能
    After 200 times freeze-thaw cycle,we found that the tensile strength of material under different treatment all showed downtrend,the tensile strength of material added fly ash by 0%,10%,35%,55% had been decreased by 29%,5%,30%,25% respectively,compared to control. Adding appropriate additive can ameliorate material performance;
