Cementis a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cements used in construction are usually inorganic, often lime or calcium silicate based, andcanbe characterized as either hydraulic or non-hydraulic, depending on the ability of thecementto set in the presence of water.
