Bearing strength of concrete VS Compressive strength of concrete
The compressive strength of concrete (fc') is a nominal material value. If you were to actually break 100 cylinders of same strength concrete though, you would get a decent amount of variability. This variability comes from different aggregate size, different w/c ratios, and other parameters.
What Equipment Is Used to Determine the Crushing Strength of Concrete ...
The crushing strength of concrete is the ability of concrete to carry a compressive load on its surface without any crack or deflection.

Compressive Strength of Concrete – Cube Test Result 7, 14, 28
Compressive Strength of Concrete at 7 Days. Concrete has the ability to gain 16 percent strength of its total strength in one day, 40 percent in 3 days, 65% in 7 days, 90% in 14 days, and around 99% strength in 28 days. So, for the M20 grade of concrete compressive strength of concrete during the day will be 13 N/mm2.
