Cold Crushing Strength - ReStaR

The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. The higher the CCS of a material is the greater should be the resistance to abrasion.

Evaluating Refractory Properties - Resco 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, the sample is broken between two flat surfaces.
