standard days of crushing concrete cubes

Crushing Concrete Cube or Cylinder at 28 days
201841 Concrete elements are designed on the basis of a 28day cube’s crushing strength. A 28day 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.
