Basalt is a common extrusive volcanic rock. An inert rock found worldwide, basalt is the generic term for solidified volcanic lava.
Safe and abundant, basalt rock has long been known for its thermal properties, strength and durability. It is formed by decompression melting of the earth’s mantle.
It contains large crystals in a fine matrix of quartz. It is a material made from extremely fine fibers of basalt. Extruded basalt stone is formed into a metal like wool composed of pyroxene, plagioclase and olivine minerals.
It is similar to carbon fiber and fiberglass, having better physic mechanical properties than fiberglass, and being significantly cheaper than carbon fiber.
This paper deals with the wide applications of basalt fiber in construction. Basalt fiber (BF), known as “the green industrial material of the 21st century”, combines ecological safety, natural longevity and many other properties.
