ASTM C39 test for compressive concrete covers the determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. ASTM C39 consists of applying a compressive axial load to molded cylinders or cores at a rate which is within a prescribed range until failure occurs.

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.

The compression machines have to be selected depending on the specimens stregth, shape and dimensions. This requirements determines the capacity of the frame, the type of spherical seat and the platen dimension.
