Iran-Made Adhesive Increases Strength, Stability of Rebar Connections to Concrete Structures
“Rebar planting adhesive is a type of glue that is used to connect rebar to structures and buildings. This type of glue is specially used in buildings and structural projects to increase the strength and stability of rebar connections to concrete structures,” said Neda Khodadoost, the sales manager of the company.
“In this new approach for the extension of concreting, new rebar is planted in the old concrete. This work is done by making a hole with a depth of about 25 cm (the exact depth of planting depends on the size of the rebar) in the concrete with a diameter slightly larger than the diameter of the rebar, and injecting glue and placing the rebar in the hole. Based on the tests, the planted rebar will withstand the cut and will not come out of the hole,” she added.
“Modification, repair, improvement, reinforcement and development of concrete structures and installation of heavy equipment on concrete bed are among the uses of this nano-based product,” Khodadoust said.
She underlined that the product, which is the result of efforts of a team of eight people, has an export certificate to Europe.
In a relevant development in November, Iranian researchers at a knowledge-based company had also designed and produced strong epoxy adhesives based on the international standards.
“Two-component epoxy adhesive for making materials (EP series) is a paste-like adhesive based on epoxy resin and amine modified hardener. Epoxy glue does not contain solvents and the amount of volatile organic substances in it is very small. This glue has extremely high adhesion and mechanical strength and creates a permanent connection,” Abdolreza Mir-Mohseni, the managing director of the knowledge-based company, told ANA.
“Also, this glue is designed and formulated for both dry and water environments. Epoxy glue is designed, formulated and produced in six different grades for different needs of the industry. Epoxy adhesives EP60, EP61, EP62, EP63, EP64 and EP65 can be mentioned among the types of these adhesives,” he added.
Noting that epoxy adhesives are used in ceramic, concrete, rebar planting, sealing and sealing, stone, wood, metals and facades, Mir-Mohseni said, “Also, high quality and 100% domestic and indigenous materials are other features of the epoxy glue.”
