The term crushing strength is also used, mainly in the context of ceramic materials. In the context of refractories, the term cold crushing strength is used for compressive strength measured at room temperature, to highlight the fact that the value does not reflect performance at high temperatures.
Categories. Most relevant lists of abbreviations for CCS (Cold Crushing Strength)
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength, compressive ...
Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100-degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.
May 26, 2015· The cold crushing strength is the resistance of the refractory to crushing, which mostly happens during transport. It has an useful indicator to refractory performance and to the adequacy of firing and abrasion resistance in consonance with other properties such as bulk density and porosity.
Purpose of the Investigation.—(1) To obtain relative values for the cross‐breaking strength of silica brick at temperatures encountered in coke oven practice. (2) To correlate the hot modulus of rupture test, if possible, with the cold modulus of rupture, or cold crushing test, either of which is cheaper and more easily conducted.

The Modulus of Rupture (MOR) indicates the material bending strength and its suitability for use in construction. It depicts the strength of the bonding system of the refractory product, and is an important parameter for quality control and development of refractory linings. For the test a rectangular test sample is supported in span. The testing machine applies a load at a specific rate to ...
Compressive strength involves testing and calculating how well a given specimen, product or material can survive compressive stress. Unlike tension, which expands or pulls, compression means a specimen, product or material is shortened or pressed down. Compressive strength of a …

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 ...
