The compressive strength of M20 grade concrete varies between 17 and 23 N/mm2 (i.e. between 170 kg/cm^2 and 230 kg/cm^2) after 28 days curing. This means that the concrete can withstand a compressive load of 170 to 230 kg/cm² before it fails.. In compressive strength test of concrete cube the push force applied on the both faces of concrete specimen and the maximum …
The cube or cylinder crushing test provides an indication of the concrete's ability to resist compression. Either cube or cylindrical mould is used for preparation of test samples. After casting the specimen on the mould, the sample is cured sufficiently for 28 days which allows the strength development of concrete.
Innovations in this test enable streamlining while ensuring quality & safety. Certified test houses are essential for the successful execution of projects. Understanding Concrete Cube Test.

Basically, the force supplied by a concrete compression machine is a definite value. For normal concrete strength application, say below 50MPa, the stress produced by a 150mmx150mmx150mm cube is sufficient for the machine to crush the concrete sample. However, if the designed concrete strength is 100MPa, under the same force (about 2,000kN) …
