Thanks everyone for the comments:
The EoR was concerned about strength at 28 days in initial conversations. So it would seem to me that an HES which reaches 3000 psi at 7 or 10 days would suffice. The mezzanine only will take about 10-12 days to put up, so that is what I am most concerned...
Hello -
I have a footing design requirement for a mezzanine (very long spans), that is calling for 3000 psi with 7 days cure before dead load and 28 days before live load. The engineer is on vacation now. I can't afford to wait the 28 days, so was trying to find out how long it would take 4000...
