Title: Oystein Vennesland: Innovator in Concrete Rehabilitation
Introduction
Oystein Vennesland is a notable inventor based in Trondheim, Norway. He has made significant contributions to the field of concrete rehabilitation, holding 2 patents that focus on innovative processes for enhancing the durability and longevity of reinforced concrete structures.
Latest Patents
Vennesland's latest patents include a process for rehabilitating internally reinforced concrete and a method for electrochemically re-alkalizing carbonized reinforced concrete. The first patent describes a technique that involves applying an adherent coating of an electrolytic material to the surface of the concrete. This process utilizes a distributed electrode, preferably a wire grid, embedded in the coating. By applying a voltage, chloride ions are migrated from the concrete into the electrolytic coating, effectively reducing the chloride content. The second patent outlines a method for re-alkalizing carbonized reinforced concrete by impressing an electric current between adjacent areas of concrete with differing pH levels. This process facilitates the migration of hydroxyl ions, increasing the pH of the carbonized region to a satisfactory level.
