The procedure for the crushing strength test on bricks involves the following series of steps: 1. The specimen with the mortar filled face upwards is placed in the plates of the compression testing machine. 2. The load is then applied axially at a uniform rate of 14N/ mm² per minute until failure occurs. The maximum load at failure is recorded. 3.

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 in cold condition and therefore, the determination of cold crushing strength …
