Basalt fiber bar: Reinforcement of concrete structures

This paper is review of state of art of knowledge of basalt fiber, the production methods and review of tests on basalt fiber as a strengthening material for concrete structures. There are several types of basalt fiber strengthening meth odds used to strengthen concrete. In this paper three types are mentioned: External strengthening, fiber matrixes, and rod type material.

Basalt composite bars are made by utilizing basalt fibers and a resin epoxy binder. They are non-corrosive, consist of 80% fibers and have a tensile strength three times that of the steel bar normally used in building construction. Wherever corrosion problems exist, basalt fiber composite bars have the potential to replace steel in reinforced concrete.

Compared to FRP bar as they are use for small amount in building industry the basalt bar are cheaper and have better durability under extreme conditions. It is concluded that basalt bars are of great interest for the building industry and can be used for example in bridge decks, offshore structure and in element buildings.
