How to Spec High Early Concrete for Paving
How to Spec High Early Concrete for Paving
(OP)
Here is the situation: Project to pave the entrance of an active truck terminal with concrete. Current spec is 8” of 4000 PSI Concrete (No flyash permitted) with #4 Bars placed 16” OCEW. I’d like to open the newly paced concrete to traffic after 3-4 days cure time.
How should I spec the high early concrete? 4000 PSI in 3 Days? 3500 PSI in 3 Days? Etc. Do I even need high early concrete if I extend my cure time to a week?
I know there are some long term durability concerns regarding high early concrete, so I don’t want to spec something crazy like 4000 PSI in 24 hours.
Thanks for the help.

I guess my question really should have been....At what strength can we safely drive trucks on the fresh concrete? 3000 PSI? 3500PSI?
Thanks.
