Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO3), often in the form of the mineral calcite, and frequently containing organic remains like shells and coral.

Uses:

• Building Material: Limestone is widely used in construction for walls, decorative trim, and veneer.

• Aggregate: It’s used as aggregate in concrete and other construction materials.

• Lime Production: When burned, limestone yields lime, which is used in various applications, including cement production.

• Other Uses: Limestone is also used in agriculture, in the production of paper, paint, asphalt, bricks, and metals.
