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. Refractories with high CCS are also expected to have higher ...

Acid brick installed in the bottom of an absorber tower is generally exposed to high gas temperatures in the range of 160 to 250°C. Thermal shock of the brick can occur when a dry area of the brick work is exposed to the high temperature gas and is suddenly cooled by contact with the relatively colder acid.
