Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard is a revision of JG/T 271-2010 "Building Structural Adhesives for Steel Reinforcement". JG/T 271-2010
Abolished from the date of implementation. Compared with JG/T 271-2010, the main technical changes of this standard are as follows.
--- Modified the environmental performance requirements of viscous steel glue (see 5.1);
--- Modified the mechanical performance index requirements of the steel-bonded steel adhesive for concrete-based adhesive steel (see 5.4);
--- Increase the mechanical performance index requirements for steel adhesives with steel as the base material (see 5.4);
--- Modified the situation of type inspection (see 7.1.2).
This standard was proposed by the Standard Quota Research Institute of the Ministry of Housing and Urban-Rural Development.
This standard is under the jurisdiction of the Technical Committee for Building Maintenance and Reinforcement and Real Estate Standardization of the Ministry of Housing and Urban-Rural Development.
