Cold Crushing Strength - ReStaR

The higher the CCS of a material is the greater should be the resistance to abrasion. Refractories with high CCS are also expected to have higher resistance to slag attack. 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.

Cold Crushing Strength (CCS) of Refractory Bricks - Refractory Lining

Nov 3, 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.

Properties of refractories: Refractory properties can be classified as .

The need for good abrasion resistance of refractory materials is most evident in petrochemical industries where fine particles impinge the refractory surface at high velocities at moderately elevated temperatures. A direct correlation between abrasion resistance and cold crushing strength has recently been established. Thus.
