Cure time for concrete in freezer
(OP)
I have a condition where a new concrete freezer slab will be placed at an existing building. How long does the contractor need to wait until using the freezer again? 7 days for proper cure time? Thanks!






RE: Cure time for concrete in freezer
After curing, a temperature drawdown schedule should be followed to prevent excess cracking from thermal shrinkage and to allow moisture to be removed from the concrete more slowly to mitigate drying shrinkage and to dehumidify before reaching freezing temperatures.
ACI 302 has recommendations for a drawdown schedule (assuming you are in the US).

You will have to consider phasing of work as well as treatment of joints. Also a temperature drawdown schedule will have to be implemented. The guy responsible for the mix design should be able to give you curing,shrinkage,etc. Parameters.
