ASTM International’s composite materials committee (D30) has developed a new standard specification for the latest generation of fiber reinforced polymer (FRP) reinforcement bars. Rebar Coupler Without Thread
According to ASTM International member Francisco De Caso, this new standard (D8505) is a milestone after several decades of collaboration to further integrate these composites into infrastructure. “The higher performance specified for bars, results in a significant improvement of design and construction of concrete structures reinforced with non-metallic FRP bars," says De Caso, principal scientist at the University of Miami, Florida. “This translates into more efficient and sustainable design of concrete structures."
De Caso also notes that the specification contains critical contributions such as the inclusion of basalt FRP bars to existing glass FRP bars, as well as higher-performance bars. He also says that the standard could be useful across the concrete construction value chain.
This effort directly relates to United Nations Sustainable Development Goals #6, 9, 11, and 12 on clean water and sanitation, industry, sustainable cities, and responsible production/consumption, respectively.
