Summary
Basalt is a hard, black extrusive igneous rock formed from rapidly cooling volcanic lava, rich in calcium and magnesium oxides, found on Earth, Mars, and the Moon. In construction, crushed basalt builds road bases, drainage filters, concrete for railroads, bricks, and slabs. Farmers use its rock dust as fertilizer to boost plant growth and curb weeds, while its high tensile strength makes melted composites ideal for pipes, rebars, and wind turbine blades.

I read about basalt rock when I was in school, so I can answer your query on what is basalt rock. It is a very hard, black, extrusive igneous rock that can be found not only on Earth but also on Mars and Earth's moon. This rock forms from volcanic lava that cools rapidly on the surface of Earth. It is usually black in colour due to the high amounts of calcium oxide and magnesium oxide, and very low amounts of lighter coloured silicate minerals.

Now you know what rock type is basalt.

What is Basalt Used for Construction

There are many uses of basalt in construction. For example, crushed basalt is used in making the base for pavements and roads, as filter stones in drainage projects, and as a part of concrete mixtures for making railroads. The rock is also employed in sheets and slabs for creating bricks, tiles, and other stone objects to construct buildings and large monuments.

Agriculture

Several gardeners and farmers employ basalt rock dust fertilizer because not only does it help increase the growth of plants but also makes it hard for weeds to spread in flowerbeds.

Industrial Manufacture

The tensile strength of this rock is very high, it’s much greater than carbon fiber/fiberglass. Therefore, melted composites of this rock are used for manufacturing pipes and rebars that are further used in constructing wind turbine blades.

Other Uses
  • This rock is used in the groundwork or is used for construction purposes of blocks and buildings.

  • It is also used for making statues.
