What Is The Characteristic Strength Of Concrete
If a block of M25 concrete has a characteristic strength of 23 MPa means that the chances of failure are only 5 at that load 23 Mpa 95 chance is there it will survive The compressive strength test will be determined by the strength of concrete at 28 days as per IS standard Based on the cube test results the below graph was plotted.

Crushing Value The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied Test Method IS 9376 1979 IS 2386 P 4 1963 Drying Shrinkage Drying shrinkage is defined as the contracting of a hardened concrete mixture due to the loss of capillary water.
Compressive strength
In mechanics compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size as opposed to tensile strength which withstands loads tending to elongate In other words compressive strength resists compression being pushed together whereas tensile strength resists tension being pulled apart .
