摘要：

Laboratory studies were undertaken to compare chloride (Cl-) profile data to predictions obtained using ASTM C 1202 of Cl- diffusion into concrete. The effective diffusion coefficients (D(eff)) derived can be used to determine long-term Cl- profiles of concrete structures. Equations relating D(eff) with resistivity and permeability of concrete were developed. One- and two-dimensional models were used to determine Cl- profiles of Cl- ions entering concrete in structures such as square piles and decks.
