Basalt Rebar for Concrete Reinforcement
topic
Basalt fibre reinforced polymer rebar replaces steel reinforcement in concrete structures with corrosion-immune pultruded basalt-epoxy bars achieving tensile strength of 1000 to 1200 megapascals, elastic modulus of 50 to 60 gigapascals, and complete immunity to chloride-induced corrosion that causes concrete cover spalling in marine and de-iced infrastructure environments over multi-decade service life.
Role
Addresses the multi-billion dollar global cost of steel rebar corrosion damage in coastal, marine, and winter road infrastructure by providing a permanently corrosion-immune structural reinforcement that eliminates the concrete cracking, spalling, and structural deterioration initiated by steel corrosion expansion, extending infrastructure design life beyond 100 years without maintenance interventions.
