Oxidation is the process of oxygen pulling away electrons from another molecule. These molecules, with an uneven number of electrons, become unstable and begin reacting with other molecules around them. Called free radicals, these volatile compounds are the root cause of browning, aging, rusting, and in the coffee world, staling.

Concrete grinding is the process of smoothing rough concrete surfaces. During the concrete grinding process, an abrasive tool with diamond attachment smooths the rough surface. All coatings, stains, and surface cracks are removed along with the top layer of concrete during the first step in the process. Deeper cracks must be evaluated.

Relief is usually not noted until polishing begins, so it is important to begin the preparation with grinding media that will keep the samples as flat as possible. However, for the best possible starting conditions, MD-Largo should be used for fine grinding of materials with a hardness below 150 HV, and MD-Allegro should be used for fine ...
