T/CECS 220-2007 Concrete structure durability evaluation standard
Basic Information
Scope
Main technical content: This standard is applicable to the durability assessment of concrete structures in existing buildings, bridges, and general structures, but not to lightweight aggregate concrete and special concrete structures. Concrete structures with additional anti-corrosion measures can refer to this standard for assessment. The main contents include: general principles, terminology and symbols, durability assessment criteria and basic procedures, investigation of usage conditions and durability testing, durability assessment of reinforcing steel corrosion in atmospheric environment, durability assessment of reinforcing steel corrosion in chloride-induced corrosion environment, durability assessment of concrete in freeze-thaw environment, alkali-aggregate reaction and stray current corrosion assessment, component, component item, and structure durability assessment, etc.
