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.View More

Cold crushing strength and high temperature crushing strength of refractory brick. Cold crushing strength. Cold crushing strength is the ultimate load per unit area of dense shaped refractory products can withstand without damage at room temperature The cold crushing strength of pressure resistant refractory products has a great impact for the production, transportation and use performance.View More
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.View More
