Crushing Concrete Cube or Cylinder at 28 days

2018-4-1  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.
