Compressive Strength. The compressive strength of any material is defined as the resistance to failure under the action of compressive forces. Especially for concrete, compressive strength is an important parameter to determine the performance of the material during service conditions.
Concrete Crushers, Concrete Pulverizers | NPKCE
Cutting-torch operations are eliminated by a replaceable high-strength, steel center cutter that slices through rebar and light steel structures. Faster, more efficient separation of concrete and steel rebar. Powerful concrete crushing forces increase when jaws meet resistance, as the exclusive NPK cylinder intensifier converts flow to pressure.
CIP 35 - Testing Compressive Strength of Concrete
The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures. The compressive strength is measured by breaking cylin-drical concrete specimens in a compression-testing machine.

Crushing Strength of Reinforced Concrete Membranes
The importance of the membrane crushing strength rather than the concrete crushing strength in the determination of the mode of failure and in the design and analysis of membrane structures such as shearwalls and shells is demonstrated. An illustrative example of the methodology is included.
Properties of concrete - Wikipedia
In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.
