Why cubes are tested at 3, 7 and 28 days for the Compressive Test?
The reason for testing concrete before 28 days on these days as well is that suppose the concrete strength falls fairly inadequate on let's say 7 or 14 days. Then, the concrete may straight away be discarded or another mix design be made. Or else, better curing can be done. This will save time, money and effort.
