Methods to Assess the Drying Ability of Refractory Castables

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

“…These pressure levels could be reached during the drying of the castable, as shown by the pressure-temperature-mass (PTM) tests conducted by Fey et al [29], where a maximum gas pressure of 1.8 MPa was measured for a composition with polymeric fibers heated at a rate of 0.93°C/min. Similar pressure levels were also reported by Meunier et al [30].…”

“…Interest regarding the drying behavior of refractories is also driven by the potential reduction of the economical and environmental costs associated with the monolithics processing. Studies ranged from laboratory‐scale thermogravimetric tests (TGA) 9–11 to those based on pressure and temperature sensors, 12–14 or even more advanced techniques, such as nuclear magnetic resonance (NMR) 15,16 and neutron tomography 17 …”
