GB/T 28721-2012
ActiveCathodic protection of reinforcing steel in atmospherically exposed concrete structures
大气环境混凝土中钢筋的阴极保护
Application Summary AI generated
This standard specifies the technical requirements, design, installation, commissioning, operation, and maintenance of cathodic protection systems for reinforcing steel in concrete structures exposed to atmospheric environments. It is applied to protect against corrosion in bridges, buildings, parking garages, and other infrastructure where chloride ingress or carbonation has compromised the passive layer on steel reinforcement. The standard is used by engineers and maintenance personnel to ensure long-term structural integrity and extend service life in atmospheric exposure conditions.
