Dang, least it would be quick.

Just to be the pedant in the thread, that is actually a concrete mixer. Cement is just one ingredient of concrete.

Pedant is the right word.

'Cement mixer' is a significantly more common term than 'concrete mixer', and not an incorrect one since it indeed mixes cement.

Actually, around here that would be a cement truck. A "mixer" is one of those small jobbies on two wheels that you tow to a work site behind a pickup. And you hang it from a crane 100 feet up at night so it won't get stolen.

Both do the same thing. One is on a truck, the other is not.

More common does not mean correct. You don't mix cement. You mix concrete. Cement is just an ingredient of concrete. Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Yes, lots of people use cement and concrete interchangeably. They are all incorrect.

And you should run for Congress on that platform.

That's prescriptivist thinking, which is wrong in this case.

Terms change in meaning with how they are used. There is no unchanging definition of words.

Concrete mixer and cement mixer are synonymous now. They may not have always been, but now that they are used interchangeably by a lot of people (your words), they are synonymous.

That's how languages in general, and English in specific, works.

Cement mixer is an incorrect term. It's a concrete mixer.

We would get a firm talking to in my materials class if we ever refered to concrete as cement.
