ICCP and Electrochemical Treatments

IMPRESSED CURRENT CATHODIC PROTECTION, CHLORIDE EXTRACTION, AND RE-ALKALIZATION FOR CONCRETE BRIDGES Impressed current cathodic protection (ICCP) systems have successfully been used to protect embedded reinforcing steel from corrosion in bridge structures since the early 1970s. Since then the field has evolved with respect to new innovations in material science and practitioners have learned many lessons as it relates to the design, installation, and maintenance of these systems. This webinar will discuss the history of ICCP systems, modern approaches to design and current applications on bridge structures. 0:00 Intro 3:28 Overview 4:41 How a Corrosion Cell Works 10:27 Cathodic Protection 13:30 Cathodic Polarization & Protection Criteria 18:45 Selecting an Anode System | Conductive Coating 21:27 MMO Overlay 23:15 Impressed Current Metalizing & Conductive Grout 29:00 Determining Current Demand 35:18 Circuit Resistance 38:49 Current Distribution 43:20 Steel Framed Masonry Bridge - Case Study 46:16 Electrochemical Treatments 49:57 Q&A
