Evaluating Refractory PropertiesResco Products
Cold crushing strength measures the compressive strength of a refractory. The test is performed at room temperature after drying or firing. Refractories are ceramic materials and are stronger in compression than in tension. In the cold crushing strength test Cold crushing strength is the maximum load per unit area applied under specified conditions at room temperature that a refractory product will withstand before failure occurs.

Industry.Guru Cold crushing strength
Cold crushing strength (CCS) of a refractory brick represents its strength. That is it tells us how much load that refractory can bear in cold conditions. The concept of testing CCS of a refractory material has perhaps come from metallurgy. This is because for any refractory brick it is rather rare that it would fail simply due to load on it In the context of refractories the term cold crushing strength is used for compressive strength measured at room temperature to highlight the fact that the value does not reflect performance at high temperatures. Compressive strength is almost always cited for ceramic materials where it is substantially higher than compressive strength.
