| 摘 要： | 选用钢纤维、聚丙烯纤维及混杂纤维掺入轻骨料混凝土进行抗冻性试验.对冻融循环试验结果研究,提出基于动弹性模量衰减的纤维轻骨料混凝土冻融损伤模型.比较发现模型采用直线方程与一元二次方程的分段型数学模型拟合精度高.并根据损伤理论分析掺入不同纤维对轻骨料混凝土冻融损伤速度的影响,结果说明掺人混杂纤维优于聚丙烯纤维及钢纤维.

| Abstract: | Steel fiber,polypropylene fiber and hybrid fiber are selected to incorporate into lightweight aggregate concrete of the frost resistance experiment.The research to establish a model of freeze-thaw damage of fiber reinforced lightweight aggregate concrete for relative dynamic elastic based on experimental results has been done.The model with the line and square is superior to the other.Based on the damage speed,incorporate into hybrid fiber is better than steel fiber and polypropylene fiber. |

| Keywords: | fiber reinforced lightweight aggregate concrete relative dynamic elastic freeze-thaw damage model damage theory |
