From crisp packets to concrete buildings the European Cement Industry demonstrates how everyday waste fuels cement manufacturing CEMBUREAU s response to The Guardian s Concrete Week Eurelectric and Energy-intensive industries call for an ambitious and comprehensive EU Industrial Strategy to enable industry s contribution to the EU The wet method uses water to cool the diamond abrasives. The water reduces friction and acts as a lubricant eliminating any grinding dust. The resin bonded grinding disks can melt at high temperatures. The water keeps them cool and increases their life span. The wet process of polishing concrete creates a slurry on the surface which is a
Polished Concrete ProcessSteps for Polishing Floors
Polishing Process The process begins with the use of coarse diamond segments bonded in a metallic matrix. These segments are coarse enough to remove minor pits blemishes stains or light coatings from the floor in preparation for final smoothing. Depending on the condition of the concrete this initial rough grinding is generally a three- to four-step process.
