The most common material in the world is concrete

Concrete is used more than any other material worldwide, which may not come as a surprise given the accessibility of the aggregates and water needed to make it. Concreting in Alumy Creek, is used more than any other material worldwide. Perhaps even more startling is the fact that 20 billion tons are used annually, with China accounting for half of the world's annual production and consumption of concrete!

Concrete Driveways in Alumy Creek and cement are not interchangeable terms

To assume "concrete" and "cement" are interchangeable is akin to claiming "flour" and "cake." Only 10% to 15% of concrete is cement, which is mostly composed of lime; the remaining 60% to 65% of the material is an aggregate like sand or gravel, and the remaining 15-20% is water.

During World War II, concrete was employed to identify enemy planes

Surprisingly, "sound mirrors" made of concrete were employed to warn of approaching planes during the start of World War II. At first, they were equipped with microphones and possessed an astounding audible range of approximately 27 miles.

Exceptionally strong compression

Although it can go as high as 20,000 psi, concrete typically operates at between 3,000 and 7,000 psi. Concrete construction is demonstrated by the fact that the Colosseum, Hadrian's Wall, and the aqueduct at Pont du Gard in southern France are still intact. 

High-rise structures and motorway bridges are made of concrete

Concrete decking is used on almost all motorway bridges because they are less expensive and easier to maintain than steel ones.
