Concrete Cube Testing Explained
Crush the cubes to test their strength – When each cube is ready for testing, it is put into a concrete crusher. This machine exerts force onto the cube until it breaks. The rate at which it crushes is measured, and this is its compressive strength. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of
