Bricks, Masonry, Asphalt and Concrete - exposed aggregate concrete

are there any sites on the web that would give information on how to make an exposed aggregate surface... If I were to put little pebbles in a 3' by 4' concrete bed, or if I were to use some other aggregate. Where also could I get ideas on what to use as an aggregate?

Thanks.

I don't know of any websites to help you, but as far as what kind of material you can use, you can virtually use any type of stone or whatever that you want to. You just broadcast (spread) over the top of the concrete after you first bullfloat it, then float it in. The rest is timing. Just before the surface is set, you wash the concrete off the stones or material that you want exposed. Then after full cure you can come back and wash the material with a light acid mix to clean it. Then you should seal it with a good quality sealer. Hope this helps
