Evaluation and Performance Monitoring of Corrosion protection Provided by Fiber-Reinforced Composites

摘要

Corrosion damage of reinforced concrete structures has become an extremely costly maintenance item throughout the world. Many of the structures affected are those in or near marine environments. An increasingly popular repair and rehabilitation method for these damaged structures is the application of a fiber-reinforced composite wrap to the concrete surface. The main objective of this project is to use electrochemical techniques to determine the corrosion conditions of components of a bridge structure before and after rehabilitation using a fiber-reinforced composite wrap. In addition, the performance monitoring of the bridge structure wrapped with a commercial system will be described. A laboratory test program has been developed to simulate cylindrical and rectangular components of the bridge system and this program will complement the field testing. The purpose of the laboratory program is to simulate field conditions and investigate the effects of a number of parameters considered important for corrosion control.
