The following research projects will receive funding from the ACI Foundation:
Standard Critical Chloride Threshold Test Variability due to Material Sources: principal investigator Ceki Halmen, University of Missouri - Kansas City. Endorsed by ACI Technical Committee: 222 Corrosion of Metals in Concrete. 
The large variability of published CT data and lack of a standard CT test method creates significant difficulties for the concrete industry. Researchers cannot compare CT values obtained from their research to a standard value. Practitioners evaluating condition of reinforced concrete structures for maintenance and rehabilitation cannot make a reliable assessment based on measured chloride contents. Designers cannot estimate the service life of their design without a reliable estimate of critical chloride threshold value. Development of a standard critical chloride threshold test with a complete data set regarding its variability will alleviate these issues. ....
