Apr 06, 2002 · Re: concrete topping on existing slab Hi Ed, You should probably have submitted this in Materials & Techniques but I'll take a shot at it here. In order to do an overlay that will truly last, you'll need to abrade the surface of the existing slab to give it teeth and then coat it with a bonding agent, before you can add the new layer.

Although we usually apply densifier after grinding with the 80-grit metal-bond diamond, we have also had good success applying densifier after the color has been applied, around 400 grit. When it comes time to applying densifier to concrete that will be acid stained or dyed, the timing differs.
All concrete polishing surfaces use agents to harden the concrete, and make it denser. The main job of the hardener agent is to make the concrete hard, so that it can be easily polished. The compacting agents make the concrete floor dense or thick, so that it becomes water-resistant, stain-free, and shiny for a longer period of time.
Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4). This is calcium sulfate with a .
Grind the concrete floor using a 30- to 40-grit metal bonded diamond. Once you've finished, grind the floor again with an 80-grit metal bonded diamond. Then, move up to a 150-grit bonded diamond or something finer, if necessary. At this point in the process, apply a chemical hardener to the floor's surface to densify the concrete.
