Potassium monofluorophosphate
Potassium monofluorophosphate is found to be superior to sodium monofluorophosphate as a corrosion inhibitor for steel reinforcement members in reinforced concrete; conveniently the potassium monofluorophosphate in aqueous solution is contacted with a surface of the reinforced concrete to facilitate penetration of the potassium monofluorophosphate into the concrete.
