Crushing strength | geology |
The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch. Testing machines and extensometers for compression tests resemble those used for tension tests.

Effect of Rate of Loading on Compressive Strength of Concrete
As the time required to test the concrete cubes at 140 kg/cm2/min is high, it is not followed on site. As concrete grades ranging from M20 to M40 are usually used, they were selected for the project. It is also observed that the time taken to test a cube is 20 seconds to 1 min which generates the rate of loading as 900 kg/cm2/min to 1400 kg/cm2/min.
