A composite stonelike material formed by mixing an aggregate (such as stones of irregular shape or crushed rock) with cement (which acts as the binding material) and water, then allowing the mixture to dry and harden; portland cement, now used in making concrete, was not developed until the 19th century. Also see average concrete, cyclopean concrete, poured concrete, reinforced concrete.
