What is next if we miss concrete cube crushing on …
The only reason we test at 28 days is to compare the field cast cubes against the lab cast design cubes. Usually an earlier test is done at 7 or 14 days to see if the material is on track to achieve strength at 28 days before more work is added to the material being tested. If you are not sure that the material will make strength in 28 days, be diligent to perform the acceptance tests at 28 days or as soon as …

The cubes are removed from the curing tank, dried and grit removed. The cubes are tested using a calibrated …
ACCEPTANCE OF CONCRETE COMPRESSIVE STRENGTH
compressive strength of the 28 days old sample cubes with edges of 150 mm, mix cured, according to MSZ EN 1992-1-1:2005 until the compressive strength class of C50/60. So by the approach of MSZ EN 1992-1-1:2005 for example the concrete of C25/30 compressive strength class at the age of 28 days, mix cured, should have a minimum mean compressive strength determined using cubes with 150 mm …
What Next, If Concrete Cubes Failed After 28 days ...
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.
