An Overview: Basalt Rock Fibers – New Construction Material

Glass, carbon, and polyamide fibers are commonly used in manufacturing the reinforcing bars for concrete applications. Recent developments in fiber production technology allow the making of basalt fiber which is made from basalt rock.

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.

This technology was mainly developed in the USSR. Basalt fiber has such properties as a good range of thermal performance, high tensile strength, good electromagnetic properties, inert nature; and resistance to acids, radiation, UV light, vibration, and impact loading.

This paper deals with their manufacturing processes. It also disscusses the availability of a variety of forms of basalt fibers products and their applications as new construction materials and technique. The average tensile strength and modulus elasticity of BFRP bars were found to be about 1090.2MPa and 42.78GPa respectively.

The basalt fibers are mainly manufactured in Eastern Europe, Russia, and the USA, now in Israel and China. Finally, it is concluding that this is a low cost material, which it is possible to manufacture in India due to the availability of basalt rock (nearly 5, 00,000 sq. km).
