The compressive strength of the 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.

Compression tests (ASTM C 39) are conducted to determine the compressive strength of concrete (or its ability to resist a crushing force). In this test, a standard test load is applied parallel to the longitudinal axis of a pre-molded and properly cured concrete cube of a standard size (BS 1881—125:2013).

In evaluation of concrete test results, the within-test range R of a strength test result is found by subtracting the lowest single cylinder strength from the highest single cylinder strength of the two or more cylinders used to comprise a strength test result. The average within-test range is used for estimating the within-test standard deviation.

The test is usually conducted in batching laboratories. In order to conduct the compressive strength test, a small sample of concrete mix is first cast in a cube or cylinder form and allowed to age for 28 days. For concrete samples that contain additional material, a longer curing time of 56 days is recommended.
