Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. In other words, we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. Based on the test results, conformity can be checked as per the relevant standards.
By KAUSHAL KISHORE Materials Engineer, Roorkee The examination and compression testing of cores cut from hardened concrete is a well established method, enabling visual inspection of the interior regions of a member to be coupled with strength estimation. Other properties which can be measured is also given in this paper. IS 456-2000 specified that

1. In general, a lot of literature is available on compressive strength of cube or cylinder specimens. However, in practice, reinforced concrete is used in the field, especially for large structures.
ASTM C109 specifies the testing of hydraulic cement mortars, which involves compressing 2-inch 50 mm cube specimens to failure. For compression testing of concrete cubes we used an Industrial Series 150LX Model universal testing machine with Partner Software and a spherically seated compression platen assembly that met the alignment requirements of the standard.

It is an acceptable test for mortar but take care that the result you get is only for the 50mm cubes. This value is not similar to the standard value obtained by the 150mm cubes.
The Compression Testing Machine is a very common testing method that is used to establish the compressive force or crush resistance of a material and the ability of the material to recover after a specified compressive force is applied and even held over a defined period of time by measuring fundamental variables, such as, strain, stress, and deformation.
