Properties of Novel Basalt Fibre Composite Bars for Reinforcement in Concrete Structures

In recent years, numerous efforts have been made to find an alternative to reinforcing steel in order to achieve improved properties such as corrosion resistance and a slender design of concrete elements. A promising approach is the use of non-metallic fibre-reinforcement polymers (FRP) for reinforcement of concrete structures. Basalt fibres have great potential in this respect due to their excellent properties such as high tensile strength, corrosions resistance and low weight. These fibres from natural rock can be produced in an environmentally friendly way and have excellent recyclability compared to glass or even carbon fibres. In this study, two different bar diameters made of basalt fibre reinforced polymer (BFRP) are evaluated with regard to their mechanical properties depending on their structure.
