Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid. It is the second-most-used substance (after water), [1] the most widely used building material, [2] and the most-manufactured material in the world. [3]
Cement is a fine powder made from calcined limestone and clay that acts as a hydraulic binding agent. Concrete, on the other hand, is the actual structural material created when you combine cement with water and aggregates like sand and crushed stone.
concrete, in construction, structural material consisting of a hard, chemically inert particulate substance, known as aggregate (usually sand and gravel), that is bonded together by cement and water. Among the ancient Assyrians and Babylonians, the bonding substance most often used was clay.
Concrete is an artificial construction material prepared by mixing a binding material (cement or lime), fine aggregate (sand), coarse aggregate (stone chips, brick chips, or gravel), and water in proper proportion. Admixtures may be added to improve specific properties of concrete.
Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar.
