Cold crushing strength – The capacity to endure the rigors of transportation and handling prior to the installation of refractories in the furnace is determined by the cold crushing strength. In conjunction with other parameters such as bulk density and porosity, it can be used as a good indicator of the adequacy of firing and abrasion resistance.
