Types of stones used in the construction | Basalt, Granite ...

Basalt is an igneous rock, formed by the solidification of molten magma under pressure. Basalt has a medium to fine-grained structure. These stones are basically used as road metals. It has a specific gravity of 1.8-2.9 and a compressive strength of 200-350 N/mm2. Basalt is mostly in dark grey to black in colour.
