  • Cold Crushing Strength (CCS) of Refractory Bricks and

    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 metallurgyCold 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 pressureresistant refractory products has a great impact for the production, transportation and use performance, so higher cold crushing strength is betterCold crushing strength and high Wanhao RefractoryThe 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 abrasionCold Crushing Strength ReStaR
