Effect of fiber reinforcement on residual properties of high-strength concrete under elevated temperature
High-strength concrete shows particular characteristic behavior at elevated temperatures, such as explosive spalling, that is rarely observed in normalstrength concrete. This behavior has been attributed to the very dense concrete matrix usually associated with high-strength concrete. This paper presents the effect of fiber reinforcement an mitigation of explosive spalling and residual properties of high-strength concrete under elevated temperatures (600 deg C). The experimental work has been carried out an the influence of three parameters associated with fire resistance. These three parameters are an addition of polypropylene fibers and/or polymer beads, the moisture content of the concrete and the water to cement ratio. The experimental results showed 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 three conditions were reduced in the test specimens.
