A standard cement truck holds 8-10 cubic yards of concrete.
A typical ready-mix cement truck carries 8-10 cubic yards (about 20-25 tons) of concrete per load. Capacity varies based on truck size, axle configuration, and local weight regulations. Smaller trucks may hold 5-7 yards, while larger models can reach 12+ yards for specialized projects.
Factors Affecting Cement Truck Capacity
- Truck size: Standard trucks hold 8-10 yards; mini-mixers carry 3-5 yards.
- Weight limits: Legal axle load restrictions may reduce maximum volume.
- Concrete density: Heavy mixes (e.g., with aggregates) lower yield per truck.
- Drum design: Larger rotating drums increase capacity but add weight.
Cement Truck Sizes and Capacities Compared
| Truck Type | Cubic Yards | Weight (Tons) | Best For |
|---|---|---|---|
| Mini-Mixer | 3-5 | 7-12 | Small residential jobs (patios, sidewalks) |
| Standard Mixer | 8-10 | 20-25 | Driveways, foundations, medium projects |
| Large Mixer | 10-12+ | 25-30+ | Commercial slabs, high-volume pours |
How to Calculate Yards Needed for Your Project
- Measure area: Length × Width × Depth (in feet) = Cubic feet.
- Convert to yards: Cubic feet ÷ 27 = Cubic yards.
- Add 10% extra: Account for spillage or uneven subgrades.
- Divide by truck capacity: Total yards ÷ 8 (standard truck) = Number of loads.
What Happens If You Overorder?
- Extra fees: Some suppliers charge for unused concrete (per yard).
- Waste disposal: Hardened concrete requires special disposal (added cost).
- Shortened work time: Concrete begins curing within 90 minutes of mixing.
Alternatives for Small or Large Projects
- For <5 yards: Use pre-mixed bags (80 lb = ~0.66 cu ft) or trailer-mounted mixers.
- For 10+ yards: Request a "short load" fee waiver or schedule multiple trucks.
- For 50+ yards: Consider on-site batching plants or conveyor systems.
