Concrete Bridge Protection and Rehabilitation: Chemical and Physical Techniques.Feasibility Studies of New Rehabilitation Techniques

摘要

The objective of this study was to examine and develop feasible chemical methodsfor the corrosion protection of reinforcing steel in concrete bridges. A broad spectrum of chemicals were evaluated, corrosion inhibitors, chloride scavengers, and polyaphrons. Screening tests were developed to evaluate inhibitor effectiveness and their ability to penetrate concrete. The evaluation of the inhibitors led to the recommendation of various types of inhibitors with potential application in reinforced concrete as well as 3 different treatment techniques.
