2015/05/26Cold Crushing Strength is also highly important in case of insulating refractory bricks where bricks have to be porous as well as strong. The Cold Crushing Strength can be determined by following the steps given in any of the Standard Methods for Refractory Testing like - ASTM, Indian Standards (IS), Ghost, DIN etc. CCS is not a measure of performance at elevated temperature.

The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. 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

Compressive strength is obviously relevant to the structural performance of the blockwork - but it has no relevance to the sound insulation performance of the separating wall. The compressive strength of a block is not directly related to its dry density. Indeed, there are a wide range of options when it comes to considering which block to use.
