Method for Determination of Chloride Content of Fresh Concrete
Also Known As:
The DD 216:1993 standard outlines a volumetric method for measuring the chloride content in fresh concrete. The method involves the use of a silver nitrate solution and provides simplified procedures that are suitable for use on construction sites.
By using this standard, construction professionals can accurately determine the chloride content in fresh concrete, which is crucial information for assessing the potential for corrosion of reinforcing steel within the concrete structure. The standard specifies the use of a silver nitrate solution, which reacts with chloride ions to form a white precipitate of silver chloride. The amount of silver nitrate solution required to reach the endpoint of the reaction indicates the chloride content in the concrete.
The standard also emphasizes the importance of following the correct procedures to ensure accurate results. It provides guidelines and instructions for the preparation of the silver nitrate solution, sample collection and handling, and the titration process. The procedures outlined in the standard are designed to be user-friendly and suitable for on-site testing, facilitating efficient and reliable chloride content determination in fresh concrete.
