发明名称 Method for inhibiting corrosion of metal imbedded in concrete
摘要 The corrosion of ferrous-based metals imbedded in concrete containing a chloride is inhibited by drawing the chlorides away from the metal, and then applying a composition containing ammonium carbamate or ammonium carbonate to the concrete. An agent may be added to the solution to prevent any calcium hydroxide contained in the concrete from precipitating the corrosion inhibitor.
