Amazing data about cement

China used more cement between 2011 and 2013 than the U.S. used in the entire 20th Century.

It’s a statistic so mind-blowing that it stunned Bill Gates and inspired haiku. But can it be true, and, if so, how? Yes, China’s economy has grown at an extraordinary rate, and it has more than four times as many people as the United States. But the 1900s were America’s great period of expansion, the century in which the U.S. built almost all of its roads and bridges, the Interstate system, the Hoover Dam, and many of the world’s tallest skyscrapers. And China and the U.S. are roughly the same size in terms of geographic area, ranking third and fourth in the world, respectively.
