Standard Test Method for Compressive (Crushing) Strength .
1.1 This test method covers two test procedures (A and B) for the determination of the compressive strength of fired whiteware materials. 1.2 Procedure A is generally applicable to whiteware products of low- to moderately high-strength levels (up to 150 000 psi or 1030 MPa).
Crush Resistance Testing :: JLW Instruments
This is a common test used in packaging design and validation. Compressive strength is the capacity of a material or structure to withstand axially directed pushing forces. When the limit of compressive strength is reached, brittle materials are crushed. Usually, a crush resistance test involves a load limit.

The test results indicated that there is a good correlation between the some shape properties of aggregate and compressive strength Keywords: Aggregate shape, Digital image processing, Concrete, Compressive strength
Pavement materials: Aggregates - Civil Department
Crushing test One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.
