Cement

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together There are two main forms of cement: Geopolymer cement and Portland CementCement is seldom used on its own, but rather to bind sand and gravel togetherCement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.
