The different compositions formed using cement are Mortar, Concrete, Reinforced Cement Concrete.
Concrete is a mixture of fluid cement with coarse silica and it hardens over time. Mortar is a workable pasty mixture made using cement and is used to bind the building blocks together such as stones, bricks or concrete masonry blocks, for filling and sealing gaps between them. Reinforced cement concrete is a composition of concrete with a reinforcing material such as steel, polymers or alternate material. The reinforcement increases the tensile strength and ductility of the entire mixture.
