Cold Crushing Strength - ReStaR

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 (Crushing) Strength :: MakeItFrom

Compressive (Crushing) Strength. Amount of compressive stress at the onset of failure. The definition of failure tends to vary with material type. As with tensile tests, the terms ultimate and yield can be used. However, ductile materials do not break during compressive testing, and therefore have no ultimate compressive strength.

Answer (1 of 3): Compressive strength is the load (measured in pounds/sq. in. or /sq.ft.) which the concrete (poured over a solid base) will support, without damage. Specifically, by being crushed. If the load gets large enough, the concrete will fracture and be crushed. The crush strength is th...
