Basalt Fiber Properties, Advantages and Disadvantages

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.

Strength and durability of basalt fiber and basalt

Basalt fibers melt drawn from naturally occurring igneous rock in an inert atmosphere of helium, argon or nitrogen show significantly improved mean strength (3.7 GPa). Weibull analysis of fiber strengths at different gage lengths indicates a high-strength population governing strength below 6.5-mm gage and a low-strength population at higher

Basalt Rock Fibre

Advantages of basalt rock fibers. They have no toxic action with air water. Reduces the width of the cracks. The thickness of the concrete layer can be reduced to half. Very high chemical resistance. Basalt is the best reinforcement for concrete due to its tensile strength. The fibre can be easily mixed.
