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 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 as strong.
For the measurement of the CCS, according to EN 993-5, a steadily increasing compressive load is applied to the refractory sample by a compressive machine until the sample fails.
The EN993-5 Standard is issued in 1998 and is based on the PRE/R14 elaborated in 1967.

Stock products: 2-3 working days after deposit.
For custom products: 2 weeks after deposit.


Sample: Usually shipped by UPS, FEDEX, DHL.
Note: Refractory bricks can not be transported as above.

Firebrick by brick joints size and operating the fine degree is divided into four categories. The categories and brick joints size respectively is: class I, class II, less thanless than or equal to 0.5mm; 1mm; class III, IV, is less than or equal to 2mm less than or equal to 3mm. System of rotary kiln refractory lining with fire clay masonry, the mortar joints should be less than 2mm, the construction should be strictly controlled. Realequipment lining mortar joint fire clay should be full, and the upper and lower inner and outer brick joints shall be staggered.
