Cement powder, here conditioned in bag, is mixed with fine and coarse aggregates and water. A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel aggregate together. Cement mixed with fine aggregate
