A standard ready mix truck carries up to about 10 cubic yards of concrete, though many plants load 8 to 9 yards to stay within legal weight. Smaller trucks carry 3 to 6 yards, and some larger ones carry more.
Typical truck capacities
A full size ready mix truck commonly carries 8 to 10 cubic yards. Mini mixers and volumetric trucks carry about 3 to 6 yards or mix on site as needed.
A cubic yard of concrete weighs about 4,050 pounds as a planning value, so a 10 yard load is about 20 tons of concrete. That is why many plants load a little under the drum size.
Why the minimum matters
Many plants set a minimum order, often a few cubic yards, and charge a short load fee below it. Ask about the minimum and the fee when you order.
If your project is only 1 or 2 yards, ask about small load or mini mixer options, or mix bags yourself.
How long can the truck wait?
Concrete starts to set soon after mixing. Plants usually allow a limited unloading time, and extra time on site can cost extra. Have forms, helpers, and tools ready before the truck arrives.
Ordering the right amount
Calculate your volume, add 5 to 10 percent for waste, and round up to the next quarter yard. Running short is more expensive than having a little left over.
