| 摘 要： | 通过钢纤维混凝土试件的冻融循环试验,研究了钢纤维体积率、冻融循环次数、混凝土强度等级对冻融循环作用下钢纤维混凝土基本力学性能的影响,探讨了钢纤维对混凝土的增强机理.试验结果表明:混凝土强度等级较高时,钢纤维体积率对混凝土抗冻性能的影响比较显著.钢纤维的加入以及混凝土强度等级的提高是改善钢纤维混凝土抗冻性能的有效途径.

| Abstract: | Through the experiment on freeze-thaw for concrete specimens,the influence of the grade of concrete strength was studied,the volume fraction of steel fiber and the freeze-thaw circulation times on the basal mechanics performance of steel fiber reinforced concrete after freeze-thaw were tested.Furthermore,the reinforced mechanism of the steel fiber reinforced concrete under the action of freeze-thaw was discussed.The study results showed that when the grade of concrete strength is higher,the influence of ste... |
