Crushing Concrete Cube or Cylinder at 28 days

1/4/2018 In most common concrete elements, such as columns, beams, slab-on-grades, and conventional suspended slabs, we start crushing cubes at 7 days. The reason is that it is the time the cast concrete can be loaded, and we can proceed with the following construction activities, but only if the compressive test report at 7 days has passed the condition of 80 percent of the specified strength.
