Basalt fiber introduction

Basalt rock can be used to make not only basalt bars but also basalt fabrics, chopped basalt fiber strands, continuous basalt filament wires and basalt mesh.

Some of the potential applications of these basalt composites are: plastic polymer reinforcement, soil strengthening, bridges and highways, industrial floors, heat and sound insulation for residential and industrial buildings, bullet proof vests and retrofitting and rehabilitation of structures.

At Structural and Composite Laboratory at Reykjavik University (www.sel.ru.is) have been ongoing several researches about strengthening concrete beams and columns by basalt FRP materials in past years. These tests have shown improvements in strength and durability compared to unstrengthen concrete members.
