What is Compressive Strength? Definition from Corrosionpedia

Compressive strength is measured on materials, components and structures. By definition, the ultimate compressive strength of a material is that value of uniaxial compressive stress reached when the material fails completely. Measurements of compressive strength are affected by the specific test methods and conditions of measurement.

METHODS TO QUANTIFY THE PARAMETERS APPLIED IN

The uniaxial compressive strength of the rock constitutes the highest strength limit of the actual rock mass. ISRM (1981) has defined the uniaxial strength of a rock to samples of 50 mm diameter. A rock is, however, a fabric of minerals and grains bound or welded together. The rock therefore includes microscopic cracks and fissures.
