Concrete, hardened: Chloride content by volhard titration (NT BUILD 208s)

NT BUILD 208s

  • This Nordtest method can be used for determination of the total chloride content in hardened concrete by dissolving the concrete dust in a solution of nitric acid followed by Volhard titration. Another possibility is to use potentiometric titration which gives better precicion and accuracy. This method is not described here.
