Rapid In Situ Determination of Chloride Ion in Portland Cement Concrete Bridge Decks
A chloride ion specific electrode is used for rapid in situ analysis of the chloride content of Portland Cement Concrete bridge decks. Insertion of the chloride specific electrode into 2.5cc. of a borate-nitrate solution in a 3/4 inch diameter hole drilled in the bridge surface provided chloride analysis to plus or minus 0.5 pounds of chloride per cubic yard in 95% of the samples in 90 seconds. The system is applicable to bare concrete surfaces or concrete surfaces under asphalt overlays. A sample collection method is presented that allows rapid sampling with little or no contamination. The equipment cost is small and training of personnel is not difficult. Time benefit ratio of previous to present method is about 7 to 1.
