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.
Common materials and average ultimate compression and tension strength.
In almost all loading conditions, metals fail in compression by plastic flow.* The compressive strength is then simply the yield stress of the metal. .
From my opinion the Compressive strength at 28 days is just the verification at the beginning stage in properly maintenance conditions , but is not finally value.
