摘　　要：为了测试MAMF增强混凝土的耐高温性能,通过对高温后MAMF增强混凝土的抗压强度试验,探讨了其抗压强度在不同温度下的变化规律,分析了温度对混凝土力学性能的影响机理。研究结果表明,MAMF纤维混凝土的抗压强度随温度的升高而变化的规律。并通过对比高温后MAMF纤维混凝土和聚丙烯纤维混凝土的抗压强度,表明掺入MAMF纤维的混凝土具有很好的耐高温特性。To test the high temperature resistance heat of MAMF reinforced concrete,through testing the compressive strength of MAMF（multi-functional asbestos modify the fiber）reinforced concrete after high temperature,the compressive strength variation of MAMF reinforced concrete under different temperature was discussed.The impact mechanism of temperature on the mechanical properties of concrete was analyzed.The results show that the compressive strength of concrete increases with the temperature rising.And by comparing the compressive strength of MAMF and polypropylene fiber concrete after high temperature,mixed with MAMF concrete has good high temperature properties.
