Most trucks are 10 and 11 yard trucks. I think 11 yard Mixers are most common.
concrete is measured by the yard, and a concrete truck filled to the top of spout will hold nine yards, so a full truck of concrete is the whole nine yards.
A person may be able to purchase an concrete truck at a ready-mix company that can be ordered, or added along with, the amount of concrete that a person or company is providing. For example, the general rule is that a concrete truck will, about average, hold ten cubic yards. Again, this is average because some trucks will actually hold about eight cubic yards to about nine cubic yards.
Most will hold 10 cubic yards. Some local codes will force them to run 8 or less because of the weight.
The term "yards" of concrete means cubic yards.
It is typically measures in cubic yards. Anything over 2 cubic yards is a lot of mixing, so you'd likely want to order that from a concrete company in a ready mix concrete truck.
