Crushing Concrete Cube or Cylinder at 28 days | Quality ...
Apr 01, 2018 · Why We Crush Concrete Cubes or Cylinder Samples at 28 Days. If the cube has a failed test result at 28 days, then your spares will be used to test on either 42 days or 56 days, depending on what test age you prefer beyond 28 days. Two cubes will be tested again with the same cube ID number, but these will be spares.
