RE: Concrete Curing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
James,
The curing is not dependant on any particular concrete age or strength. Any deviations from the recommendations can be accommodated by developing a test and analyzing the results from a test pour.

Concrete specs normally call for maintaining the concrete in a damp condition for 5 days at 70 degrees or 7 days at 50 degrees F. I believe that this is for 28 day concrete.

If I want to use say 3000 psi at 5 days, how should the above requirement be changed?
