Study of an Innovative Construction Material - “Basalt Fiber”

Abstract

Basalt fiber (BCF) is an inorganic fiber material. It is an all-natural material and originates from volcanic rock. Basalt rock is melted at high-temperature (1450° C) and rapidly drawn into a continuous fiber. It then can be chopped into various lengths. Its color can vary between brown, gold, or gray. The basic characteristics of Basalt materials are high-temperature resistance, high corrosion resistance, resistance to acids and alkalis, high strength and thermal stability. Basalt materials can be used as a reinforcing composite material for the construction industry, specifically as a less expensive alternative to other fiber. In addition to high specific strength, high specific modulus, BCF also has excellent temperature resistance (-260~700_), anti-oxidation, anti-radiation, thermal and sound insulation, filtration, anti-compression strength and high shear strength, high availability, and good cost performance. It is found in nature as an inorganic non-metal material and is a new basic material and high-tech fiber that can satisfy the demand for the development of basic infrastructures.
