Concrete as a building material has been around for a very long time. In Yugoslavia, some has been identified which is thought to be over 7000 years old. It is present in the pyramids at Gizeh and the Romans used it in the Pantheon and in aqueducts in France, where it is still performing well. The earliest surviving Australian examples date from the 1860s and ’70s.
Concrete today is an indispensable part of the fabric of modern society, used for everything from mundane road pavements and high rise building structures to the more exotic such as ferro-cement yacht hulls.
