TEHRAN - An Iranian technological company has produced a nano-based adhesives which facilitates the repair and development of concrete structures and is economically cost-effective for the construction of structures.
Rebar planting adhesive is a two-component epoxy resin-based material that, when injected into the drilled hole in the concrete, the two components are simultaneously combined and create a strong mechanical and chemical bond between the rebar and the concrete substrate.
This product, which is offered in cartridge, tube and sausage packaging, can be used in acidic, alkaline environments and various climatic conditions and is suitable for installing heavy machinery and equipment on concrete foundations, reinforcing concrete sections in bridges, highways and water conservancy projects.
The nanotechnology used in this product provides features like high adhesion, chemical resistance and mechanical durability against seismic loads and harsh environmental conditions. This adhesive was developed to meet the needs of domestic construction projects based on geotechnical studies, seismic and climatic conditions and complies with the national and international standards, including CE certification.
In a relevant development in March, an Iranian knowledge-based company had managed to apply nanotechnology to produce cement-based tile powder adhesives for construction uses.
Abolfazl Zare’ Bidaki, the managing director of the knowledge-based Bidak Nano Sakhtar Sanaye’ Shimiyayee company introduced a cement-based tile powder adhesive containing nanoparticles as one of the products of his company.
“These advanced adhesives, using silica nanoparticles, can provide higher mechanical strength than conventional products and establish a better bond between the tile and the wall surface,” he said.
“In the past two to three years since this adhesive has been supplied to the market, we have tripled its sales every year,” Zare’ Bidaki said.
