but you don't have to pay for a deputy inspector. Note that I said "end
up with 4000 psi". My point is that it is not usually necessary to
specify more than 2500psi. "
Thank you Stan! I've always wondered why so many specs list a relatively low strength but require w/c = 0.40 or even lower, guaranteeing that the concrete would be much stronger than the specified strength. Now I know. But why is it done outside the UBC area?
