Abstract

The use of fiber reinforced polymer (FRP) rebars avoid the accelerated deterioration that reinforced concrete structures suffer due to the corrosion of the steel reinforcement. FRP composite rebars are made of longitudinally aligned fibers embedded in a polymeric resin, being E-CR glass the predominant type of fiber in the FRP rebar industry. However, in the last decade the use of basalt fiber has increased significantly due to the enhanced mechanical properties and reduced environmental impact compared to E-CR glass.  

This paper lists the main properties that BFRP rebars have, summarizes the existing standards and specifications including the new ASTM specification for basalt fibers, and evaluates their use through existing practical construction projects. The aim of this article is to create a frame of reference to introduce the necessary tools for professionals in the construction industry to use BFRP rebars in lieu of steel where non-corrosive reinforcement is needed to extend the service life of the built infrastructure.
