“…Indeed, according to pioneer investigations, it is shown that various factors, such as the physical and/or mechanical properties of fibers [25][26][27][28] and concrete matrices [29][30][31], fiber fractions [32,33,22], specimen preparation and curing methods [34,35], heating procedures [36,37], temperature ranges [1,38], specimen sizes [33,39], etc., influence the thermal spalling performance of concrete in different ways. However, few analytical studies are available for quantitatively elaborating the governing mechanism of concrete spalling through which the aforementioned influencing factors take effect.…”

“…Although the strength, workability, and durability of HSC are usually much superior to NSC at ambient temperature [10], its failure is sometimes rapid and dramatic when subject to elevated temperatures, characterized by spalling [11]. Many researches have confirmed that HSC is more prone to spalling than NSC when exposed to high temperature [12][13][14][15]. However, some inconsistent results have been reported concerning the characteristics of spalling, in which different critical temperatures for appearance of this phenomenon have been reported.…”

“…Polypropylene bers have been widely used for the reinforcement of cementitious materials to improve the toughness and energy absorption capability of the matrix [6]. Ozawa and Morimoto [7] carried out permeability tests on high-strength concretes (72 MPa) including 0.15% volume of polypropylene bers (PPF). Results showed the residual permeability increasing 12 times after heating the PPF concrete to 500 C compared to the reference concrete.…”
