The Concrete Facts about Trump鈥檚 Wall and China
Did China use more concrete in three years than the US in the 20th Century?
If the US is going to build a wall on their border with Mexico 鈥� it鈥檚 going to take a heck of a lot of concrete - millions of tonnes in fact. But as Wesley Stephenson finds out there is a unlikely winner from all this construction. But even with such a huge construction project the US is still a minnow when it comes to concrete use and it is often said that China used more concrete between 2008-2011 than the US did in the whole of the Twentieth Century. It sounds astonishing - but is it true?
