DR. Shakouri Receives ACI Foundation Concrete Research Council Grant



Dr. Shakouri's proposal entitled "Chloride Desorption Isotherms of Cementitious Systems Exposed to Low-pH Environment" was one of the eight finalists that received 2021 CRC funding.

The overall objectives of this project are to understand the kinetics of chloride desorption mechanisms and develop empirical chloride desorption isotherms for cementitious systems that contain ordinary portland cement (OPC), fly ash, slag, and silica fume. Given that the knowledge of available free chloride content in the pore solution is essential for a reliable service‐life estimate, this project will fill this knowledge gap by developing empirical desorption isotherms incorporated in service‐service life models. The data from this project is expected to provide the baseline for addressing the disassociation of bound chlorides in ACI 222 and 365 documents. Moreover, a standardized test will be proposed for measuring the chloride desorption capacity of cementitious systems.
