crashing strength of concrete
Crushing or Crush Concrete Cubes or Cylinder at 28 days
The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28

Nominal Bearing Strength of the Concrete Calculator
Compressive strength - Compressive strength is is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. (Measured in Kilogram-Force per Square Meter) Area of supporting concrete - Area of supporting concrete is geometrically similar to and concentric with the loaded area.

What Is The Characteristic Strength Of Concrete?
The characteristic strength of concrete is the result of the compressive strength of the concrete cube test. The design strength is the required strength of concrete to be designed as per the IS code. For example, assume that the strength of concrete required M25, and the target design strength is 28.5 N/Sqmm.

Concrete Lab Report | Concrete | Strength Of Materials
Compression tests (ASTM C 39) are conducted to determine the compressive strength of concrete (or its ability to resist a crushing force). In this test, a standard test load is applied parallel to the longitudinal axis of a pre-molded and properly cured concrete cube of a standard size (BS 1881—125:2013).

Properties of Concrete Blocks — Strength
In the use of concrete blocks for the walls of buildings, the stress to which they are subjected is almost entirely one of compression. In compressive strength well-made concrete does not differ greatly from ordinary building stone.
