Ⅰ. What is Concrete?
Concrete is a composite material composed of coarse granular material (the aggregate or filler) embedded in a hard matrix of material(the cement or binder) that fills the space among the aggregate particles and glues them together.
Concrete is widely used for making architectural structures, foundations, brick/block walls, pavements, bridges/overpasses, motorways/roads, runways, parking structures, dams, pools/reservoirs, pipes, footings for gates, fences and poles and even boats.
Famous concrete structures include the Burj Khalifa (world`s tallest building), Hoover Dam, the Panama Canal and the Roman Pantheon.

The United States produces about 156 billion pounds (71 billion kilograms) of portland cement a year, which is about 7 percent of the world’s total. Other major cement producers include China, Germany, Japan, Korea, and Russia. The leading states are California, Michigan, Pennsylvania, and Texas.
The production of ready-mixed concrete ranks as the biggest single concrete industry in North America. About 4,000 U.S. firms and about 1,200 Canadian firms produce ready-mixed concrete. More than 60 percent of the cement produced in the United States is sold to ready-mix producers. The second largest branch of the concrete industry is the manufacture of precast concrete for construction.
