What is the minimum curing time for refractory cast in mock-up panels?

The minimum curing time for refractory cast in mock-up panels is recognized as 12 hours. This timeframe is important to allow the material to achieve adequate strength and hardness, ensuring that the refractory material can properly set and bond during the curing phase.

Curing is critical because it involves maintaining moisture and temperature to help the chemical reactions that develop strength in the refractory. A minimum curing period of 12 hours is generally necessary to reach sufficient initial set, enabling the mock-up panels to be handled safely and tested without compromising the material’s performance characteristics.

Shorter curing durations would not allow the appropriate bond and structure to form, potentially leading to failure during subsequent testing or in service. Longer durations, while beneficial for certain aspects, are not considered the minimum required for adequate curing in this specific context.
