高温下聚丙烯纤维混凝土抗压强度试验研究

A Study of Compressive Strength For Polypropylene Fibre Concrete In High Temperature

通过对高温后的聚丙烯纤维混凝土和素混凝土抗压强度的试验研究,着重分析了不同纤维含量、不同纤维长度在不同温度场下对混凝土抗压强度的变化规律和影响程度。研究结果表明,无论纤维混凝土还是素混凝土抗压强度均随温度升高逐渐降低,且纤维的含量在一定范围内对混凝土强度影响较小。

The compressive strength of polypropylene fiber reinforced concrete（ PFC） and normal concrete under high temperature is studied by experiments,the changing law and the influencing degree for the compressive strength of concrete in different fiber content and length under different temperature were analyzed. Through experimental study,The results show that the compressive strength of polypropylene fiber reinforced concrete（ PFC） and normal concrete decreases with increasing temperature,fiber content in a certain range,has a smaler effect on the compressive strength of the concrete.
