Cement - Wikipedia

Cement is often supplied as a powder, which is mixed with other materials and water. A cement is a binder, a substance used for construction that sets, hardens and adheres to other materials, binding them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together.
