Some Amazing CaCO3 Accomplishments


800px-mount_rushmore_national_memorial.jpgMount Rushmore, near Keystone, ND, shows the great facades of our Presidents, comprised of almost complete granite, which is a rock that includes calcium carbonate deposits. The strong molecular structure of the rock alled for dynamite to blast through the stone cliff.


In 1984, The Statue of Liberty was closed so that a $62 million renovation could be performed. Concrete was a part of that renovation because in the places where the paint corroded the internal copper skeleton, and where steel was inappropriate to use, concrete was used to reinforce the areas. So in a way, CaCO3 was a part of the reason why the Lady is still standing today.

The Hoover Dam, the world’s largest complete concrete structure, is a $49 million dollar accomplishment that allows passage from Arizona to Nevada, holds back millions of gallons of water, and generates 2,080 megawatts of electrical power to hundreds of homes. Up to 10 million people visit each year. CaCO3 saves the day again.450px-hooverdam.jpg
