We are on a site where unsuitable soils are to be removed up to 3 or 4 feet below planned bottom of footing (BOF). Flowable fill (no air, 300-500 psi) can be used to re-establish original BOF. Can anyone tell me the recommeded length of curing of the flowable fill prior to normal-wt concrete...

I'm sorry. Misunderstood the ? WD = 120.9; DD(calculated) = 102.2; MC = 18.3% Thx
