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.

The main activity of Global Basalt Engineering LLC is creation of effective productions on release of continuous basalt fiber (СBF) with technologies of the last generation and composites on the basis of СBF (Basalt Fiber-Reinforced Polymer Composites as BFRP).

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.
