Concrete Compressive Strength Variation with Time
The compressive strength gained by concrete is thus measured at its 28th day after which the rate of strength is lowered. The compressive strength gained at later ages are tested by means of non-destructive tests. The table-1 below shows the rate of strength gained from the first day to 28th day. Table.1: Strength Gained by Concrete With Age.

How does Compressive Strength relate to Bearing Capacity
The "unconfined" compressive strength is equal to 2 times the undrained shear strength. For all intents and purposes the ultimate bearing capacity is 6 times the undrained shear strength (where c in cNc is the undrained shear strength) or 3 times the unconfined compressive strength.

Uniaxial Compressive Strength
Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.

The higher the compressive strength of rock, the higher also is its quality, which plays an important role particularly in road construction. A material’s compressive strength is delineated into hard, medium-hard or soft rock, which also determines the crushing techniques used for processing to obtain the desired particle sizes.
