Hi Ron , thanks for your answer.
The concrete for those two floors were of 25 mpa.During the curing period the concrete was kept soaked for two weeks with a plastic on top and was monitered constantly through out this time.The stone size was 3/4 inches.We used super plastifier to keep the water to a minimum inside the mixture.Now after this we installed an ashford formula wich is a lifetime sealer.The humidity level of 45% should be an improuvement compare to all regalar warehouse where they do not keep any level of humidity.We also filled up some joints with 150% expandable epoxy in some areas.Our thinking was that by sealing these control joints we were protecting any moisture going in.The result was that no difference was noticeable between where it was done and not
