Concrete is a composite mixture of rough granular material mixed with cement that helps fill the space among the aggregate particles and glues them together. Concrete is widely used to make architectural structures, walls, pavements, bridges, reservoirs, dams and highways among others such as runways, parking structures, pipes and even boats. In the UAE, the Burj Dubai stands as the world’s tallest building and is still under construction. The building’s height has reached 1,921 feet, totaling 156 floors. The frame is structurally reinforced concrete with a structural steel spire at the top.
