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 test cube manufacturing and curing procedures
The strength of concrete is generally measured by testing concrete cubes which are prepared from the concrete used in that particular construction. The cube strength of concrete is specifi ed by a structural engineer and is assessed by crushing concrete cubes at a specifi ed age (28 days after casting).

Concrete Cube Testing
In some extreme cases, many cubes are taken, and the tests carried out every few days, but as a general rule, the 28-day strength is taken as the target. 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.

So,100mmx100mmx100mm concrete cubes can be utilized in place of 150mmx150mmx150mm cubes to raise the applied stress to crush the concrete cubes. For normal concrete strength, the cube size of 150mmx150mmx150mm is already adequate for the crushing strength of the machine.
