Cement is made from limestone and clay or shale through a heating process, creating compounds crucial for its composition. Portland cement grains consist of tricalcium silicate, dicalcium silicate, tricalcium aluminate, and calcium aluminoferrite. Concrete, a composite material, is formed by bonding aggregate with a cement paste, typically made using Portland cement.
Cement is manufactured from a combination of materials, primarily calcium carbonate (limestone) and clay or shale. When heated in a kiln, these materials transform into various compounds such as tricalcium silicate, dicalcium silicate, tricalcium aluminate, and calcium aluminoferrite, which are essential components of Portland cement.
Throughout the process, the chemical composition of Portland cement grains comprises these minerals. The limestone used in cement production is obtained from quarries and plays a fundamental role in producing the necessary calcium silicate compounds.
Concrete, on the other hand, is a composite material made of fine and coarse aggregate bonded with a cement paste. The cement paste in concrete, often made with Portland cement, hardens over time, resulting in a durable construction material.
