Chloride Limits in Concrete is the new topic in NRMCA's Technology in Practice series (TIP 13). TIP 13 addresses the limits on internal chlorides in concrete as addressed in the Building Code, ACI 318. It discusses reasons for the limits, sources of internal chlorides, testing for chlorides and discusses the calculation of chloride content in concrete from the mixture ingredients.

The Technology in Practice series has been developed by the NRMCA Research Engineering and Standards (RES) Committee to serve as brief educational discussions for ready mixed concrete industry personnel (the CIP series is developed for customers and other users of concrete).

The RES Committee requests members and others to suggest to be addressed in the TIP series. Send suggestions to Colin Lobo or Karthik Obla. Click here to view and order TIPs or contact Jacques Jenkins.
