Corrosion resistance of basalt fibers

This study describes an experimental investigation of basalt fiber, E-glass and cement-based composites resistance to various corrosive environments, including acid, salt and water solutions, and clarifies the corresponding degradation mechanisms.

Necessary rock studies of the gabbro and andesite basalt groups for the suitability as the raw material base for the production of continuous basalt fiber (CBF). A unique technique including laboratory melting and pilot-industrial melting at the high-tech equipment.

The researchers found that corrosion resistance of basalt fibers in sulfuric acid  is 4-5 times higher than that of E-glass. In addition, the beneficial characteristics of basalt fiber are said to include excellent corrosion resistance and high abrasion resistance.
