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).

We can find characteristics of concrete with the single compressive strength of the concrete cube test. With this single test, one can find whether concreting is done properly or not. For general construction work, concrete compressive strength varies from 15 Mpa (2200Psi) to 30 Mpa (4400psi) and even higher in commercial and industrial structures.

Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.
