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.
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.

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.

Insulating fire bricks, though specially designed for high heat environment, will eventually start to fail and break.
Aug 29, 2014 . Often referred to as CCS, Cold Crushing Strength measures the maximum stress needed to crush a refractory sample to structural failure in compressive loading. CCS is measured, according to ASTM C133, on typically a 2” cube. Cold crushing strength of a refractory material is an indication of its suitability.
The resonance frequency of these three bricks was first measured under flexural mode using the SonicByteTM. Their modulus of rupture (MOR), their cold crushing strength (CCS) as well as their apparent porosity were then measured according to the ASTM standard procedures. The obtained results have been used to.

S: shrinkage (%); WA: water absorption (%); FS: flexural strength (MPa); SSA: specific surface area; CS: compressive strength (MPa); CCS: cold compressive strength; λ: thermal conductivity; MRF:.
2.4. Evaluation of magnesia galaxite and magnesia chrome bricks. The physical, thermal, mechanical and chemical properties of both the bricks are evaluated and compared and are given in Table 5. The physical properties of both the bricks such as apparent porosity, bulk density, cold crushing strength, modulus of rupture.
3) Cold Crushing Strength (CCS): Cold crushing strength of refractory bricks and shapes is the gross compressive stress required to cause fracture. The cold crushing strength of the tempered and coked samples was measured as per ASTMC-133. The test samples were cut from the standard brick samples. Cold crushing.
Aug 20, 2015 . Effect of coal size on bulk density and cold crushing strength is also evident. Finer coals lower the bulk density but increase the cold crushing strength.

refractory brick in order to classify the properties of the bricks. One of the most important and used mechanical characterization methods is the CCS-test, cold crushing strength test, a uniaxial compression strength test at room temperature (RT). This test is usually used as guidance to a brick's mechanical strength. Naturally.
