Light Weight Concrete on Pan Deck

RE: Light Weight Concrete on Pan Deck
Lightweight can be a real bear to get dried out, but the process is the same as for standard weight concrete.

Be sure the surface is open and porous. If it is sealed with chemicals or burned black by a steel trowel you should grind or blast the surface open.

Warm air holds more moisture than cold air. Warming the air and the slab will promote moisture transfer out of the concrete.

Moving the air and bringing in drier air also promotes moisture movement out of the slab. Dehumidifiers can help a lot.

If all else fails or you don't have the time you can always use a mitigation system.
