对纤维高强混凝土受热后的力学性能和渗透性能进行了试验研究。将圆柱形混凝土试样以10摄氏度/分钟的速率加热至400摄氏度。为了研究短纤维对高强混凝土高温后剩余性能的影响，在混凝土中掺入聚丙烯纤维和钢纤维。聚丙烯纤维增强高强混凝土的残余性能显著降低是由于其纤维成分的熔化和汽化。在无损检测方面，UPV试验被认为是一种很有前途的火灾受损混凝土结构初始检测方法。此外，还研究了混杂纤维对纤维高强混凝土加热后剩余性能的影响。(C)2006爱思唯尔有限公司保留所有权利。
Mechanical and permeability performance of fibre reinforced high strength concrete after heat exposition were evaluated in the experimental study. Cylindrical concrete specimens were exposed to heat with the rate of 10 degrees C/min of up to 400 degrees C. In order to study the effect of short fibres on residual performance of heated high strength concrete, polypropylene and steel fibres had been added into the concrete mix. The melting and vaporization of its fibre constituents were found to be responsible for the significant reduction in residual properties of polypropylene fibre reinforced high strength concrete. In terms of non-destructive measurement, UPV test was proposed as a promising initial inspection method for fire damaged concrete structure. Furthermore, the effect of hybrid fibre on the residual properties of heated fibre reinforced high strength concrete was also presented. (C) 2006 Elsevier Ltd. All rights reserved.
