Corrosion of Embedded Materials - PCA

When the chloride content at the surface of the steel exceeds a certain limit, called the threshold value, corrosion will occur if water and oxygen are also available. Federal Highway Administration (FHWA) studies found that a threshold limit of 0.20 percent total (acid-soluble) chloride by weight of cement could induce corrosion of reinforcing steel in bridge decks (Clear 1976).
