Concrete has been in use for millennia. Its discovery was likely by accident when limestone was “cooked” by fire and resulted in a powder that hardened. That “cement” was used with sand to make mortar and thus ancient building began.

Concrete is cement mixed with sand and crushed stone. Water is the catalyst that causes the cement to harden and bind all of the ingredients together. The Romans made great use of concrete in constructing their buildings – the greatest the world had ever seen in their day. The Pantheon is a magnificent, ancient example of the technological wonder of concrete.
