cold crushing test of refractory brick

Cold crushing strength and high temperature crushing strength of refractory brick. Cold crushing strength. Cold 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 pressure-resistant refractory products has a great impact for the production, transportation and use performance

The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature.

Cold crushing strength is the maximum load per unit area, applied under specified conditions at room temperature, that a refractory product will withstand before failure occurs. Principle A test piece of known dimensions is subjected under specified conditions to a steadily increasing compressive load until its failure, when it cannot support a further increase in load.

3.2 These test methods are for determining the room temperature flexural strength in three-point bending (cold modulus of rupture) or compressive strength (cold crushing strength), or both, for all refractory products.

The determination of cold crushing strength CCS is also highly important in case of refractory insulating bricks where bricks have to be porous as well as strong For the measurement of the CCS according to EN 9935 a steadily increasing compressive load is applied to the refractory test piece by a compressive machine until the test piece

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 does not

Was the refractory material installed improperly (i.e., porous or popcorn-like texture)? Collecting Samples for Testing: Samples of the existing refractory material should be gathered and sent out for a cold crush test, which will verify the strength of the installed material.
