    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. The size of the refractory test specimen (sample taken for testing) is usually equivalent to a 230.Aggregate Crushing Value and Its Test Procedure One of the test in which concrete material can fail is due to crushing under compressive stress.
