What is the main raw material used in the manufacturing of cement?
ALimestone
BSodium chloride
CSilica sand
DSulfur
Explanation
Cement is primarily manufactured from limestone, which is heated with smaller amounts of clay and other materials in a kiln at very high temperatures to produce a substance called clinker, which is then ground into the fine powder known as cement. When mixed with water, sand, and gravel, cement forms concrete, one of the most widely used construction materials in the world. The chemical reactions during this process release carbon dioxide, making cement production a notable source of industrial emissions.
