If the Cube test fails, as a technical supervisor what do you do on that critical situation?

Check Acceptance Criteria

  • If 28th days concrete cube test results fail checks if the result of all 7 days’ cubes is the same. If even one passes the acceptable criteria you are sure that the concrete mix is OK.
  • Even if one of the cubes is OK wait for a 28 Day result.
  • If 28 days’ result fails, then again there is a possibility that cubes are not filled properly or they were not cured properly in the first 7 days. But it is possible that slab concrete is OK. Go for the Hammer test.
  • If the hammer test is also as per failed cube result then go for core cutter and test it to get actual strength of laid concrete.
  • There are many options to strengthen a weak concrete member if concrete cube fails in test (Strengthening Techniques)
