From Rock To Fiber. Many sorts of composites which are use of the basalt fiber as the reinforced material can be used many fields such as fire, environmental protection, aerospace, armament, automotive vessels' manufacture, infrastructural material and so on.
Basalt is used in many countries around the world in highway and airfield pavement construction. As an example, in one of the basalt crushers in Poland, the production capacity of the crusher is 1,300,000 tons per year. Roads account for 70% of all this output. The fine products are used in asphalt surfacing and the coarse products are used in the underlying pavement layers.

Igneous rocks used by the ancient Egyptians include: granite, granodiorite, quartz diorite, diorite, and pyroxenite (plutonic intrusives); andesite and dolerite porphyries as well as other porphyritic rocks (volcanic dikes and lava flows); basalt and obsidian (volcanic lava flows); and tuff and related rocks (volcanic pyroclastics).
Basalt Basalt is a dark heavy lava that is very hot and fluid when it erupts. It it erupts on the continents it can flow many kilometers before it cools in thin layers. It it erupts on the continents it can flow many kilometers before it cools in thin layers.
Basalt®. A powerful, modern grey with a neutral cast, Basalt® deliberately lacks the green tones that would soften its impact when used in ultramodern designs. Exuding the strength and solidity of the rock after which it is named, the use of Basalt® lends buildings a feeling of being anchored to the earth.
Andesite. Group volcanic . Colour variable, but typically bluishgrey or grey (lighter coloured than basalt). Texture porphyritic .

Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to fiberglass, having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber. It is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to produce products such .
Basalt stones are believed to be therapeutic and have marvelous healing energy. It is commonly used for massage therapy for relaxation and healing benefits. Specifically, it is used for hot stones massage because it has magnetic iron which holds heat. Basalt stones are present during volcanic eruptions and most are found mainly in the coastal area.
