 · Wash off the concrete surface with water and a squeegee. Pour water over the top and edges of the fully-cured concrete countertop. Then run a squeegee over the entire piece to remove any debris from the surface of the concrete. Any leftover debris might dig into the concrete and leave deep scratches once you start polishing it, so make sure to remove all residue during this process.

 · The exposed diamond crystals do the grinding work. The metal matrix or bond holds the diamonds in place. Trailing behind each exposed diamond is a "bond tail" which helps to support the diamond. As the blade rotates through the material the exposed surface of the diamonds grind the material being cut into a fine powder.

Whether you are wet polishing or dry polishing, the process works like this; You begin with a coarse polishing pad and you grind the surface of the stone with it for the proper amount of time. You then repeat that action with a pad that has a finer "grit". Again, this is much like sanding wood only the process is used on stone.

This grinding is done wet or dry, depending on the process in use, but for dry grinding the raw materials first may need to be dried in cylindrical, rotary dryers. Soft materials are broken down by vigorous stirring with water in wash mills, producing a fine slurry, which is passed through screens to remove oversize particles.

 · Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.

Wet grinding of hard minerals is usually much more efficient than dry grinding. When slurry is dried in the kiln, it forms a granular crumble that is ideal for subsequent heating in the kiln. In the dry process, it is very difficult to keep the fine powder rawmix in the kiln, because the fast-flowing combustion gases tend to blow it back out again.
