Cement powder is a finely ground, dry material that serves as a key binding agent in construction, primarily used to produce concrete, mortar, grout, and plaster. The most common type, Portland cement, is made by heating a mixture of limestone, clay, and other minerals in a kiln to form clinker, which is then ground into a fine gray powder. When mixed with water, cement undergoes a chemical reaction called hydration, hardening into a strong, stone-like material that binds aggregates such as sand and gravel together. Cement powder offers high compressive strength, durability, and versatility, making it an essential component in foundations, slabs, columns, pavements, and masonry work. Available in various grades and types—such as Ordinary Portland Cement (OPC), Pozzolana Portland Cement (PPC), and White Cement—cement powder is fundamental to modern construction, delivering performance, reliability, and longevity across a wide range of building applications.
