The Arab Basalt Fiber Company is a manufacturer and supplier of basalt fiber building materials. Basalt fiber is a type of fiber made from volcanic rock basalt.
Basalt is a very common dark-colored volcanic rock composed of calcic plagioclase (usually labradorite), clinopyroxene ( augite) and iron ore (titaniferous magnetite ). Basalt may also contain olivine, quartz, hornblende, nepheline, orthopyroxene, etc. Basalt is a volcanic equivalent of gabbro. Basalt is a fine-grained and dark-colored rock.
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. Many of the picturesque views of the desert southwest show mesas and arches made of layered sedimentary rockmon Sedimentary ...
Abstract. Basalt fiber (BF), known as "the green industrial material of the XXI-century", combines ecological safety, natural longevity and many other properties. It is not a new material, but ...
Discover the amazing basalt columns of Iceland, formed by volcanic eruptions and cooling lava. Learn how they shape the landscape and where to find them.
Basalt fibers are relatively new reinforcing materials in composite production and have been widely deployed in many areas such as aerospace, architecture, chemical industry, medicine, electronics, agriculture, marine etc.
While an ancient construction material, the use of basalt to make rebar is only nine years old. Introduced to the U.S. market by Kodiak Rebar in 2013, the material is made by melting igneous rock in a furnace at 1700°C; it is then formed into long fibers by blowing filament from it—like how fiberglass is made from silicate rock.

Two varieties of basalt rocks collected from two different regions have been assessed for high-temperature packed-bed thermal energy storage. The most relevant thermo-physical and mechanical properties of the studied rocks as sensible heat storage materials were characterized.
Basalt weathers relatively fast because the iron-rich minerals are prone to oxidising, and basalt artefacts (as well as tools made from metamorphosed volcanic and sedimentary rocks) can develop a weathered outer surface that appears pale compared to the unweathered inside. The knapping quality of basalt can vary considerably depending on …
