Abstract
The invention relates to a method for protecting reinforcement in concrete from the corrosion caused by chloride ions. According to the method, metallic copper and/or copper compounds are added to the concrete mass, in which mass the copper reacts with the chloride to form salts with a chloride content and of low solubility, thus substantially reducing the danger of steel corrosion caused by chloride. The copper or copper compound can also be brought into close contact with the concrete, for example in the form of a repair mortar.
