25 bags of 60 lb: exactly on the limit
25 bags of 60 lb mix weigh 1,500 lb, which is the whole 1,500 lb payload with nothing to spare. The driver counts against the same figure, so a truck rated at 1,500 lb cannot carry all 25 within its rating. With 200 lb of people and gear the load is 21 bags.
Those 21 bags make 9.45 cubic feet of concrete, enough for 28.4 square feet of 4 inch slab. An 8 × 10 ft slab needs 60 bags, 3 trips at the full 25 bags.
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 | 1,500 lb | 37 | 25 | 18 |
| 200 lb of people and cargo | 1,300 lb | 32 | 21 | 16 |
| 400 lb of people and cargo | 1,100 lb | 27 | 18 | 13 |
| 600 lb of people and cargo | 900 lb | 22 | 15 | 11 |
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 60 lb bags (1,500 lb payload)
Each row is a 4 inch slab with no waste added, at 25 bags a trip.
| Slab | Concrete | 60 lb bags | Trips | Weight of the slab |
|---|---|---|---|---|
| 8 × 8 ft | 21.3 ft³ | 48 | 2 | 3,200 lb |
| 8 × 10 ft | 26.7 ft³ | 60 | 3 | 4,000 lb |
| 10 × 10 ft | 33.3 ft³ | 75 | 3 | 5,000 lb |
| 10 × 12 ft | 40.0 ft³ | 89 | 4 | 6,000 lb |
| 12 × 12 ft | 48.0 ft³ | 107 | 5 | 7,200 lb |
| 12 × 16 ft | 64.0 ft³ | 143 | 6 | 9,600 lb |
Worked example
1,500 ÷ 60 = 25, so 25 whole bags. 25 × 60 = 1,500 lb, the full payload. 25 × 0.45 = 11.25 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 |

Frequently asked questions
How many 60 lb bags of concrete can a truck with a 1,500 lb payload carry?
25 bags, which weigh 1,500 lb, if nothing else is aboard: 1,500 ÷ 60, rounded down. The driver, passengers and other cargo count against the payload, so with 200 lb of people and gear it is 21 bags.
Can a 1,500 lb payload carry 25 bags of 60 lb concrete?
Only on paper. 25 × 60 is 1,500 lb, the full payload, and the driver, passengers and cargo count against the same figure. With 200 lb aboard the limit is 21 bags.
How much concrete do 25 bags of 60 lb mix make?
About 11.25 cubic feet (0.42 cubic yards), at 0.45 cubic feet a bag. That pours 33.8 square feet of slab 4 inches thick.
