Crushing Failure Of Concrete Column

Crushing Concrete Cube or Cylinder at 28 days Apr 01 2018 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.
