Numerical Simulation and Experimental Set-up for Predicting the Drying Behavior of Calcium Aluminate Cement (CAC)-Bonded Refractory Castables

During the initial heating of Calcium Aluminate Cement (CAC)-bonded castables, physical and chemically-bonded water is released. Therefore, when the refractory’s permeability level is limited, pressure buildup inside the dense microstructure can take place, resulting in cracks and spalling of the ceramic lining.
