Pore pressure and explosive spalling in concrete (2008, methodology): “Explosive spalling, which refers to a sudden and violent breaking away of a surface layer of heated concrete, has been observed in many laboratory tests of HSC specimens [ 1 , 2]. This phenomenon has been generally attributed to the inability of HSC, due its low permeability, to successfully mitigat”
Geopolymer and Portland cement concretes in simulated fire (2011, methodology): “The gas fire furnace test using small cylinders has been used previously to assess concretes for spalling (Han et al., 2005, 2009; Phan and Carino, 2002).”
The influence of thermal-stressing (up to 1000 °C) on the physical, mechanical, and chemical properties of siliceous-aggregate, high-strength concrete (2013, methodology): “However, in many of these studies, the maximum temperature does not exceed 600 C [7,14,17,52,53], permeabilities are measured indirectly using chloride-ion penetration [15,51], or empirical formula, based on the volume of micropores, are used to estimate permeability [54].”
Critical factors governing the fire performance of high strength concrete systems (2007, background): “Data from various studies [ 10 ,11,14] show that the fire behaviour of HSC, in general, and spalling in particular, is affected by a number of factors.”
