Compressive strength test results are primarily used to determine that the concrete mixture as delivered meets the requirements of the specified strength, ƒ′c, in the job specification.: Strength test results from cast cylinders may be used for quality control, acceptance of concrete, or for estimating the concrete strength in a structure ...

The compressive strength of the concrete and concrete testing is must known information in structural design. Compressive strength is initially checked by doing mix design to make sure the grade of concrete considered in the structural design is achieved.

Compressive strength of concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

In the short-span compression test (SCT) the compressive strength of paper in compression mode is determined. Because only a very short length of paper (0.7 mm) is used in the test, greater account is taken of the load-bearing fiber portion of the material than with the traditional test methods (ring crush test, corrugated crush test or linear crush test).
