When most contractors think about mix design-if they think about it at all-the first
thing that comes to mind is "bags" or "sacks." In the old days, when most concrete
was mixed on site, cement was purchased in bags. A bag is 94 pounds of cement-about
1 cubic foot. But if you order a 6-sack mix, all that tells you is how much portland
cement is in the mix. That mix could be completely wrong for your application and
could even be inferior concrete. What slump do you need? What strength? Do you need
entrained air? What happens if the day is particularly cold or hot? What size of
aggregate is best? Should you ask for fly ash in the mix?
