It has been used to bring dams, test tracks, and superflat floors into tolerance. OTHER APPLICATIONSÄiamond grinding has found applications almost anywhere concrete appears. Education Master of Science, Norwegian Technology University, 1947. came to the United States, 1947, naturalized, 1954. Background Hognestad, Eivind was born on Jin Time, Norway. Recipient Engineering Service award University Illinois, 1990. CPR utilizes diamond grinding in conjunction with other techniques to cure individual causes of concrete pavement distress and simultaneously, to stop deterioration of the pavement. Eivind Hognestad, Norwegian civil engineer. It is part of an overall concept called Concrete Pavement Restoration (CPR) and is a viable alternative to expensive overlays. In recent years a considerable amount of diamond grinding has been done on the nation's Interstate Highway System. DIAMOND GRINDING FOR CONCRETE PAVEMENT RESTORATION A vacuum pick-up bar removes the cutting residue and leaves the surface relatively clean and dry. The water-cooled cutting assembly is mounted under a machine designed to precisely plane and level concrete. In the diamond grinding process diamond saw blades are stacked together on one or more shafts. They can also groove slabs to produce a skid-resistance texture, and have many repair applications. Diamond saw blades can grind out-of-spec concrete flatwork to tolerance without causing any damage or lessening the structural integrity of the surface.
