ACI 222.3R-11 Guide to Design and Construction Practices to Mitigate Corrosion of Reinforcement in Concrete Structures

ACI 222.3R-11 Guide to Design and Construction Practices to Mitigate Corrosion of Reinforcement in Concrete Structures, Corrosion of metals in concrete is a significant problem throughout the world. In many instances, corrosion can be avoided if proper attention is given to detailing, concrete materials and mixture proportions, and construction practices.

This ACI 222.3R-11 Guide to Design and Construction Practices to Mitigate Corrosion of Reinforcement in Concrete Structures contains information on aspects of each of these. In addition, the guide contains recommendations for protecting in-service structures exposed to corrosive conditions. The guide is intended for designers, materials suppliers, contractors, and all others engaged in concrete construction.
