RESCOBOND AA-22S
Why do cement bonded castables have to cure for 24 hours prior to heatup?
When water is mixed with cement-bonded castable and gun mixes, water and calcium aluminate cement will react to form hydrated calcium aluminate cement phases. Within 24 hours after mixing with water, the hydrated calcium aluminate phases will develop the maximum cured strength of a castable or gun mix, and the final hard set of a cement bonded castable. This is important to maximize physical properties during service and aid in the initial dry-out and heat-up procedure.
