    May 04, 2020 Some aggregates also contain chlorides that are trapped and probably unavailable to cause corrosion. Water-soluble chlorides, however, are not bound and can move through the concretes capillary pores. Between 50 and 75 of the total chloride content in concrete is estimated to be water soluble and a contributor to reinforcing steel corrosion. 3
