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. If they can be patched, this is the time to do so.
The course's first objective is to give an overview of the process chain within the cement industry. All the main processes involved during cement production will be discussed, including the extraction and processing of raw materials, the combustion process, cement grinding, quality control and storage, and cement distribution.
