Evaluation of a Microsilica-Based Additives in Al2O3–MgO Refractory Castables

The first heating cycle of MgO-containing refractory castables is usually considered a challenge by the producers of such products due to the significant mass loss, associated with magnesium hydroxide decomposition between 350–450 °C, that might result in their spalling or even explosion.

Refractory Concrete Behaviour for Anchored Systems under Load Induced Thermal Strain

The complex behaviour of refractory under thermal load and process conditions poses many challenges for engineers. While the use of thermomechanical analysis assuming either linear elastic conditions or non-linear fracture mechanics bases (brittle/plastic failure behaviour) is valuable, results can still lead to incorrect conclusions.
