Determination of appropriate mix ratios for concrete C20/25 concrete is expected to have a minimum cube crushing strength of 25MPa. Concrete grade/strength class C16/20 with a minimum cylinder strength of 16MPa or a minimum cube strength of 20MPa is the minimum concrete grade/strength class recommended for use in plain concrete construction [16].

In most common concrete elements, such as columns, beams, slab-on-grades, and conventional suspended slabs, we start crushing cubes at 7 days. The reason is that it is the time the cast concrete can be loaded, and we can proceed with the following construction activities, but only if the compressive test report at 7 days has passed the condition of 80 percent of the specified strength.
