Basalt fiber is a relative newcomer to fiber reinforced polymers (FRPs) and structural composites. It has a similar chemical composition as glass fiber but has better strength characteristics, and unlike most glass fibers is highly resistant to alkaline, acidic and salt attack making it a good candidate for concrete, bridge and shoreline structures.

The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 300 Mpa (Megapascal), its tensile strength: 30 Mpa, and its shear strength: 60 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong - very strong category.
