    Always get these 2 terms mixed up. But my friend just got there basement and carport cemented/concreted in. (before it was dirt) and I was wondering something. How do you get the different surface "texture" (ie fine grit or coarse grit finish) like a carport or wharehouse floor which is smooth as can be. And a regular slab of cement/concrete for sidewalks, etc.
    How do they get it really smooth, and semi-smooth from it being really rough to start off with? Do they use more sand and less gravel?
    Thanks :)

    Also just so I don't sound like an idiot, whats the difference between cement and concrete?

    As it starts to cure the workers begin to trowel it with a large machine that has 4 trowels on it and they rotate if you want it rough sometimes the drag a shop broom across it to create the texture. Also cement, is what is added to agregate (rocks) and sand to make concrete.

    Cement is concrete before it hardens.

    What really sucks is trying to finish a large slab without a power trowel. I poured concrete before joining the Air Force and we rarely had the privilege of using a power trowel.

    Always done the shop broom trick, always worked fine for us. I didn't even know about power trowels. :crazy:
