Compressive Strength of Concrete -Cube Test [PDF,
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 - Simtec
The two primary tests are the workability using the slump test and the cube compressive strength of the delivered mix. In both cases, a strict sampling technique is used to ensure the integrity of the testing. Projects and budgets can be at risk if the concrete is not tested to the relevant BS or BS EN Standards. Testing concrete can ensure it can withstand the level of
