Prob best to measure moisture ormwhat do u guys do on new construction w fresh slabs.
The CC moisture test you would perform should be what the hardwood and adhesive manufacturer recommends. Usually it is a Calcium Chloride test (ASTM F 1869), or the insitu test (ASTM F 2170).
The thirty day rule is a generalization of the time fresh concrete will harden and release most of the excess water used in the pour, merely a rough estimate.
