    950mm in diameter) on each of which there are 3–4 grinding discs of 170–270mm diameter. See Figure 2 (a, d). Each grinding disc has 3–6 diamond tools mounted on the periphery. The latter grind the surface while the discs rotate, at the same time as the head rotates with its discs.Concrete Polishing Contractors,To achieve a quality shine over the concrete surface concrete also requires much higher grinding pressure. To obtain the needed pressure, the concrete grinding machine needs to be much heavier—around 700 to 1,100 pounds, compared to the 180- to 600-pound floor machines used to grind and polish marble or terrazzo.Brickform Surface Deactivator Solomon Colors,Surface Deactivator creates a polymeric flim that acts as a water retention barrier and temporary curing agent, protecting fresh concrete from light rain and reducing moisture loss.
