ODOT was asking 3500 psi.
Also, will anyone be testing slump and air in the field on the formed work? I will do my best to collect a tickets to verify we are receiving what is being placed.

Curtis,
Here are alternate concrete mix designs for Molalla project. We were told today from Knife River that fly ash won’t be available in approx 2 weeks. These mixes put slag in the place of the fly ash. If you have any questions let me know.
Thanks,
Jim
