Compressive Strength of Concrete -Cube Test, Procedure, Results
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.

Concrete Cube Testing | Ready Mix Concrete Delivery in London
Concrete cubes are crushed and tested. Once cured and ready to test, each cube is placed into our concrete crusher, which steadily exerts force on the cube until it breaks. The rate at which the cube crushes is measured, and this gives us its compressive strength. Read our article to learn more about how cube testing works.

A Simple Guide to Concrete Cube Testing
Cube Testing The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first.

Concrete Cube Testing
For some concrete not reaching the desired 28-day strength, the crushed cube remains are submitted for chemical testing to confirm the cement content and water/cement ratio. Test cores can be drilled from hardened concrete, enabling strength tests to be carried out on older or suspect material.
