The Use of the Electrochemical Impedance Technique to Predict the Resistance to Chloride Ingress in Silica Fume and Fly Ash-Reinforced Blended Mortars Exposed to Chloride or Chloride–Sulfate Solutions

Autor: Sara Hassi, Mohamed Ebn Touhami, Bruce Menu

Publikováno v: Journal of Bio- and Tribo-Corrosion. 8

Chloride-induced corrosion is the most serious problem noted on prestressed concrete cylinder pipes (PCCPs), particularly in semi-arid environments. Since the mortar coating applied around the PCCPs protects the prestressing wires against corrosion,
