Compressive Strength of Concrete Cubes - Civilology
Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days.
A Simple Guide to Concrete Cube Testing
The concrete minimum compressive strength will be specified by the client/designer in a specific format. An example of this is given below: C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100mm concrete cylinder and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube.
Crushing Concrete Cube or Cylinder at 28 days | Quality ...
Concrete elements are designed on the basis of a 28-day cube's crushing strength. A 28-day cube's strength actually represents the characteristic strength of the concrete. It is mandatory to test the concrete cubes or cylinders at the age of 28 days as per almost all building code requirements.
Crushing strength | geology | Britannica.com
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 granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch.
Compressive Strength Of Concrete | About Civil Engineering
Hence the Crushing Strength of that cube is ( Load at Crushing/Surface Area of Cube in Contact) = (500000/22500) = 22.22 N/mm 2 .

Compressive strength - Wikipedia
The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck). The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.
