There are various types of stones that you may not have even heard of.
such as basalt, marble, quartzite, travertine, sandstone, gneiss, and granite. These stones are used as building materials.
Stones are generally extracted from hard rock mines for construction purposes. Stones used as building materials must be tough, durable and resistant to destructive agents (such as rain, sun, fog, etc.), high strength and perfect resistance.
Fragile, cracked, soft and low strength rocks will have not structural use. Depending on their toughness and resistance, the rocks will have different uses.
For example, harder rocks such as basalt and granite, due to their high strength and hardness, are more commonly used in major construction tasks – such as flooring, stairs, etc. – and lighter, less resistant rocks such as gneiss are more commonly used for Decoration
