Cement is primarily made from limestone, clay, and other materials, which are processed and heated to create a fine powder.

• Limestone: The main ingredient, providing calcium carbonate.

• Clay: Supplies silica, alumina, and iron oxide.

• Gypsum: Added to control the setting time of cement.

• Fly Ash: A byproduct from coal combustion, enhancing strength.

• Slag: A byproduct from steel production, improving durability.

Cement is primarily made from minerals like limestone, clay, and gypsum, which contribute to its strength and durability.

• Limestone: Provides calcium carbonate, essential for clinker formation.

• Clay: Supplies silica, alumina, and iron oxide, aiding in the chemical reactions during cement production.

• Gypsum: Added to control the setting time of cement.

• Other minerals: Fly ash and slag can be mixed to enhance properties and
