Basalt is a very versatile rock and is used for a variety of purposes. It is most commonly used as an aggregate, which is a crushed rock that is used to create pavement, concrete, and other materials. It is also used in construction projects and as a filler in asphalt. In addition, basalt is sometimes used as a decorative stone.

The density of basalt is in the range of 2.5–2.9 g cm −3 [28, 29, 34], which is much lower than that of steel but closer to those of carbon or glass fibres. However, basalt is far less expensive than carbon fibre and has higher strength than that of glass fibre; it has a good chance of being an ideal candidate for low-weight, less expensive ...
