2,000 lb: one ton is 25 bags
A 2,000 lb payload is one US ton, and 25 bags of 80 lb mix come to exactly that: 2,000 lb. A load that lands on the limit leaves nothing for the driver, so take people off first: 200 lb of people and gear leaves room for 22 bags.
25 bags make 15 cubic feet, which is 0.56 cubic yards. A full cubic yard is 45 bags of 80 lb mix, 3,600 lb dry, so it is 2 trips. At that size compare the price of a ready-mix delivery: a cubic yard of concrete weighs 4,050 lb placed.
Bags left after people and cargo
Payload is everything the truck carries: the driver, passengers, tools, a toolbox, a hitch and the bags. Take the rest off first.
| Already aboard | Payload left for bags | 40 lb bags | 60 lb bags | 80 lb bags |
|---|---|---|---|---|
| Nothing else aboard | 2,000 lb | 50 | 33 | 25 |
| 200 lb of people and cargo | 1,800 lb | 45 | 30 | 22 |
| 400 lb of people and cargo | 1,600 lb | 40 | 26 | 20 |
| 600 lb of people and cargo | 1,400 lb | 35 | 23 | 17 |
Use the payload on the sticker inside the driver's door of your own truck, not a figure for the model or the class. Bag weights are dry weights as sold.
Trips for a slab with 80 lb bags (2,000 lb payload)
Each row is a 4 inch slab with no waste added, at 25 bags a trip.
| Slab | Concrete | 80 lb bags | Trips | Weight of the slab |
|---|---|---|---|---|
| 8 × 8 ft | 21.3 ft³ | 36 | 2 | 3,200 lb |
| 8 × 10 ft | 26.7 ft³ | 45 | 2 | 4,000 lb |
| 10 × 10 ft | 33.3 ft³ | 56 | 3 | 5,000 lb |
| 10 × 12 ft | 40.0 ft³ | 67 | 3 | 6,000 lb |
| 12 × 12 ft | 48.0 ft³ | 80 | 4 | 7,200 lb |
| 12 × 16 ft | 64.0 ft³ | 107 | 5 | 9,600 lb |
Worked example
2,000 ÷ 80 = 25, so 25 whole bags. 25 × 80 = 2,000 lb, the full payload. 25 × 0.60 = 15 cubic feet of concrete.
Bags per load at other payloads
| Payload | 40 lb bags | 60 lb bags | 80 lb bags |
|---|---|---|---|
| 1,000 lb | 25 bags | 16 bags | 12 bags |
| 1,500 lb | 37 bags | 25 bags | 18 bags |
| 2,000 lb | 50 bags | 33 bags | 25 bags |
| 3,000 lb | 75 bags | 50 bags | 37 bags |
