Grouting temperature of pt slab.

Grouting temperature of pt slab.

Grouting temperature of pt slab.

(OP)
should a post tension slab be heated if temperature were to fall below 32F less than 12 hours after the grouting operation and if so, please explain why.

RE: Grouting temperature of pt slab.

Where do you propose to measure the temperature?

There is a big different between adjacent material temperature and just a simplistic air temperature!

The mass and thermal inertia of a concrete element takes time to change and can still be cold even with the air at 60F due to the time lag.
