Chloride Ion Contribution of Admixtures to Concrete ...

2022-1-2  ACI Chloride Limits in Concrete. Water-soluble chlorides, in combination with oxygen and moisture, can cause corrosion of embedded metals in concrete. Unfortunately, chlorides are among the most abundant materials on earth. Therefore, it is not practical to specify a maximum chloride content of “zero” for a concrete mixture.
