The Chinese Technical Specification of Electrochemical Technology for Durability of Concrete Structures was compiled on the basis of the overseas and domestic development, practice and research of durability electrochemical technology for concrete structures. The Specification stipulated the general provisions, scope of application, main parameters, quality control and inspection etc. of electrochemical technology. Main innovation of Technical Specification appears as: 1. An extensive introduction highlighted the operation and requirement of electrochemical technology for durability of concrete structures, including cathodic protection, electrochemical desalination, electrochemical deposition, bi-directional electromigration etc. 2. The mechanism and application of a new-type electrochemical technology, bi-directional electromigration, was described and its advantages were illustrated in case study. Accompanied by the implementation and application of the technical specification, the durability enhancement and control of concrete structures in China will have another level.
