Basalt
Basalt is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed bBasalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium.

A review on basalt fibre and its composites ScienceDirect
Overall basalt fibres show several advantages, which make them a good alternative to glass fibres as reinforcing material in composites used in several fields Basalt fiber is a material made from extremely fine fibers of basalt rock. It’s similar to fiberglass but stronger and more heat-resistant. It’s used in things like building materials, car parts, and fireproof textiles because it’s tough, lightweight, and doesn’t burn easily.

The aspect ratio l/d of basalt fibre fragments is equal to 20.8, higher than the critical value. Overall basalt fibres show several advantages, which make them a good alternative to glass fibres as reinforcing material in composites used in several fields such as marine, automotive, sporting equipment, civil, etc.The basalt fiber can be used in the place of glass fiber to overcome the above mentioned disadvantages. Basal fiber electrical insulation is ten times greater than that of glass fiber which makes its suitable in electrical and electronics application.

advantages and disadvantages of rocks GEOGRAPHY POINT
Here are some of the disadvantages of rocks to humans: Natural hazards: Rocks can create natural hazards such as landslides, avalanches, and mudflows. These hazards can damage property and infrastructure, and even cause loss of life. Loss of natural beauty and landscape alteration: Rocks can erode and weather, which can lead to the loss ofOn the other hand, it also has some disadvantages, such as reduced flow properties, and the price of BFs being higher than those of E-glass fibers. However, the advantages of BFs are much greater than the Crushed basalt rock is heated to a molten condition at a temperature of around 1400 °C and then passed through tiny nozzlesBasalt Fibers Reinforced Concrete: Strength and Failure Modes

Mineral fibres: basalt ScienceDirect
Basalt fibre is a type of continuous fibre prepared from natural volcanic rock and ore after melting at high temperature. The raw material for basalt fibre (andesitic basalt, andesite basalt, diabase and other volcanic rock) belongs to the family of inorganic nonmetallic silicates and is characterized by high Fe 2 O 3 or FeO content. The high Fe 2 Structure and properties. Basalt is a common extrusive volcanic rock, which is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic, containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey.Basalt Fibre an overview ScienceDirect Topics
