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

Properties for chemical stress. Chemical composition – The chemical composition of refractories is of great importance with respect to attack by liquid slags, flue dusts, glass melts and vapours. Based on the behaviour during contact reactions, the refractories can be categorized as (i) acid refractories (silica, silicon carbide, zircon cristobalite, and zircon silicate etc.), (ii) basic

The shelf life of a refractory material is determined by the exposure of the binders used in the refractory material to the environment, e.g. moisture, over the passage of time. The shelf life of a refractory material can range from 3 to 18 months depending on the manufacturer and the specific material.

Refractory has always been an integral part of steam-generating boilers. In the steam-generating industry, refractory materials are used for filling gaps and openings to help keep the fire inside the fire box, for lining ash hoppers (wet and dry) that collect ash and slag, and for the protection of lower furnace wall tubes inside fluidized bed, cyclone-fired, or refuse-derived fired boilers.

The compressive strength of the material would correspond to the stress at the red point shown on the curve. In a compression test, there is a linear region where the material follows Hooke''s law.Hence, for this region, =, where, this time, E refers to the Young''s Modulus for compression.In this region, the material deforms elastically and returns to its original length when the stress is removed.
