3-Nov-2009. 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 ...

Two types of strength tests are common. The modulus of rupture (MOR) test measures the flexural (transverse) breaking strength and the crushing strength test measures the compressive strength. Both tests have a version for cold (ambient) temperatures and high (service) temperatures. The cold crushing strength (CCS) and cold modulus of rupture ...
