Apr 25 2019 · Calcium aluminate cement and hydratable alumina are widely used in the formulation of monolithic refractories due to their promotion of initial hardening of the refractory components as well as to the green strength of the precast components (after demolding). Both these binders setting mechanisms are based on hydration reactions 3 6 .

Thermal shockWikipedia
Thermal shock is a type of rapidly transient mechanical load.By definition it is a mechanical load caused by a rapid change of temperature of a certain point. It can be also extended to the case of a thermal gradient which makes different parts of an object expand by different amounts. This differential expansion can be more directly understood in terms of strain than in terms of stress as
