分别对掺聚丙烯纤维高强混凝土和素高强混凝土高温后导热系数、表观密度进行了试验研究，分析了两者的表观密度、导热系数和导温系数的变化规律，结果表明，高温后掺聚丙烯纤维高强混凝土和素混凝土的表观密度、导热系数均呈下降趋势，高温前后掺聚丙烯纤维高强混凝土比素高强混凝土的表观密度小、导热系数和导温系数大，而且其导热系数和导温系数随温度变化规律更为明显。

The thermal conductivity and the apparent density of the polypropylene fiber reinforced HSC and plain HSC were tested and studied. The results indicate that the apparent density, thermal conductivity and thermal diffusivity of polypropylene fiber reinforced HSC and plain HSC all show downward trends after elevated temperature. Before and after elevated temperature, the apparent density of polypropylene fiber reinforced HSC is smaller than that of plain HSC, but its the thermal conductivity and thermal diffusivity are bigger those of plain HSC, and change rules of thermal conductivity and thermal diffusivity of polypropylene fiber reinforced HSC with temperature are more regular.
