Dry‐Out Simulation of Castables Containing Calcium Aluminate Cement under Hydrothermal Conditions

Can a laboratory experiment express the size effect on the drying of refractory castables?

“…Afterward, the reduced effective specific heat of this dried zone leads to the sharp increase in the heating rate until the dehydration reactions start to take place. Further investigation is needed to validate and fully understand this hypothesis, nonetheless, multiple observations in the literature can support this conjecture: i) according to Auvray et al [24] different hydrate types were detected among the phases formed during an explosion test of a calcium aluminate sample castable which were the products of a reaction that took place under hydrothermal conditions, suggesting the presence of an environment rich with pressurized water next to those specific regions.…”

“…Auvray et al (2013) tomaram em conta o risco de explosão na realização de experimentos e apresentaram a descrição da proteção que utilizaram, mostrada a Figura 103, feita de aço, com quatro maciços e chapas envolvendo todo o corpo de prova e os elementos radiativos.
