GB/T 33383-2024 Corrosion control technology of modified polyvinyl chloride structural adhesive and cement
1 Scope
This document specifies the requirements and data management for corrosion control technology of modified polyvinyl chloride structural adhesive and cement.
This document is applicable to the waterproof, impermeable and anti-corrosion design and construction of reinforced concrete (or concrete) surfaces in new, rebuilt and expanded buildings and structures. The anti-corrosion design and anti-corrosion operation of other equipment and steel structure surfaces may use this document for reference.
