What is Hydration of CAC Cement in Refractories about?

The document discusses techniques for evaluating the hydration process of calcium aluminate cement (CAC) in refractory castable matrices containing processing additives. Temperature measurements, oscillatory rheometry, and normal force tests can monitor the viscoelastic changes during cement hydration. Dispersants generally retard CAC hydration, while lithium carbonate accelerates it. These additives, when combined, provide a way to control castable setting time for suitable workability and demolding. The t
