Modelling of hygro-thermal behaviour of concrete at high temperature with thermo-chemical and mechanical material degradation (2003, background): “The material stress–strain behaviour in such conditions is highly non-linear and depends not only on the temperature and dehydration degree, but also on the history of mechanical loading during heating [29].”
Mechanical properties of foamed concrete exposed to high temperatures (2012, background): “The dehydration process in the cement paste becomes significant at temperatures above about 110 C [1] and diminishes the calcium silicate hydrate (CSH) links which provide the primary load-bearing formation in the hydrated cement.”
Investigation of the structure of heated Portland cement paste by using various techniques (2013, unknown): “When the temperature exceeds 600 C, the gel structure of C–S–H is transformed into crystalline phase gradually [24].”
Dehydration kinetics of Portland cement paste at high temperature (2012, background): “The temperature range corresponds to the dehydration of CSH is about from 105 to 1,000 C [1].”
Study on mechanism of thermal spalling in concrete exposed to elevated temperatures (2011, background): “Other desirable features in aggregates are: (1) low thermal expansion, which improves thermal compatibility with the cement paste; (2) rough angular surface, which improves the physical bond with the cement paste, and (3) the presence of reactive silica, which improves the chemical bond with the cem”
Multiphase flow in deforming porous material (2004, background): “During heating, concrete at high temperature is exposed to complicated physical and chemical transformations [17,18], causing changes of its inner structure, what has also a sensible influence on the material properties.”
Behaviour of concrete structures in fire (2007, methodology): “In prac tice, the boil ing tem per a ture range tends to ex tend from 100 to about 140 °C due to the pres sure ef fects.”
