Surface-Applied Cathodic Protection | Concrete Durability Series

GALVANIC AND IMPRESSED CURRENT SYSTEMS THAT EXTEND THE SERVICE LIFE OF REINFORCED CONCRETE Surface applied cathodic protection has been an effective option in the field of corrosion mitigation for decades, we will explore this and other new technologies that have recently come to market. This webinar will discuss how surface applied systems can be used to extend the service life of existing concrete bridge substructures in corrosive environments. 0:00 Intro 4:48 Overview 5:40 Corrosion of Steel in Concrete 9:50 Why Surface-Applied CP? 11:25 Types of Surface-Applied CP 12:27 ICCP 14:20 Galvanic CP 15:40 Big Creek Bridge - Case Study 21:03 Yaquina Bay bridge - Case Study 27:15 System Monitoring 28:17 ECE 30:32 Garden City Skyway - Case Study 36:37 Ontario MoT Bridge Deck Overway 38.32 Surface Mounted Distributed Galvanic Anode 45:00 Autostrade Italy - Case Study 47:10 Summary 48:50 Q&A
