Basalt composite rebars (BCR) have been introduced recently into the market as an alternative to steel bars. They offer a number of advantages over the conventional steel bars as well as FRP bars.
Their light weight combined with non-corrosive nature will result in economic and sustainable reinforced concrete structures. BCR is an ideal choice for applications such as marine structures, off-shore structures, parking structures, bridge decks, highway under extreme environments, and structures highly susceptible to corrosion (paper and chemical industries) and for pervious concrete pavements.
