Limestone is the main ingredient in cement production.

Limestone is the primary raw material used in the production of cement. It is heated in a kiln along with other materials like clay and gypsum to produce clinker, which is then ground into the fine powder known as cement. The high calcium content of limestone makes it ideal for this process, as it reacts with other materials to form compounds that harden into the solid, durable material we use in construction. Cement is essential in the building of infrastructure, roads, and buildings, making limestone a critical mineral in the construction industry.
