The term 'Component of Concrete' refers to two of the main ingredients used in the production of concrete, namely CEMENT and SAND. CEMENT is a powdery substance made from a mixture of elements that includes calcium, silicon, aluminum, and iron. It acts as a binding agent when mixed with water and aggregates such as SAND or gravel. SAND is a granular material composed of finely divided rock and mineral particles. It is an important component of concrete, providing bulk, strength, and resistance to wear. Together, CEMENT and SAND form the basis of concrete, which is used in a variety of construction projects.
