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.LOI is a measure of the water content of the ore and an important step in iron ore analysis. When ore is fed into a blast furnace, the water contained in it will evaporate.
