Calculating concrete accurately prevents ordering expensive extra ready-mix trucks or running out during a pour.
Bag Yield Rates
One 80lb bag yields 0.60 cu ft. One 60lb bag yields 0.45 cu ft. One 50lb bag yields 0.375 cu ft. For projects larger than 2 cubic yards (~54 cu ft), ordering ready-mix truck delivery is typically more cost-effective than hand mixing.
