 · 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. Now, once your 7-day test and even your 14-day test have passed, you will then wait for the 28-day test.

 · In using this test procedure, you are assuming concrete has a significant plastic strain range. It does not. In compression, it truly acts as an elastic material, but you are likely to get multi-axial stress increases that will fail the sample prior to the onset of localized crushing, usually in a shear or shear-tension mode.
