本文研究了纤维增强对高温（600 ℃）下高强混凝土爆裂和残余性能的影响。试验研究了与耐火性相关的3个参数对耐火性能的影响。这3个参数是聚丙烯纤维和/或聚合物珠的添加、混凝土的含水量以及水与水泥的比率。结果表明，内部温度升高减轻了试样中含有的纤维或珠，通过加热，低水泥水比，和高水分含量被熔化。在这些条件下加热引起的伴随应变在试样中减少。
This paper examines the effect of fiber reinforcement on mitigation of explosive spalling and residual properties of high strength concrete under elevated temperatures (600 deg C). The experimental work was conducted on the influence of 3 parameters associated with fire resistance. These 3 parameters are an addition of polypropylene fibers and/or polymer beads, the moisture content of the concrete, and the water to cement ratio. Results show that the internal temperature elevation was mitigated in the test specimens that contained the fibers or beads, that were melted by heating, by low cement-water ratio, and by high moisture content. The accompanying strains due to heating at these conditions were reduced in the test specimens.
