The history of concrete dates back to ancient Rome, approximately 2,000 years ago. The so-called “Roman Concrete” is composed of limestone, volcanic ash, and seawater and it permitted the construction of aqueducts, highways, and temples; many of them still stand to this day. Some time ago, this original mix was discovered to form a mineral called aluminum tobermorite, which gets stronger as time goes by.
Since then, concrete has undergone various innovations. The base product is Portland Concrete, which is made of calcareous stone heated to 1,450ºC and was patented in the 19th century. It is worth mentioning that pure concrete is naturally brittle. It was the French gardener, Joseph Monier who developed reinforced concrete by combining the traction resistance of metal and the compression resistance of concrete, thus being able to withstand heavy loads. This way, the correct mix between concrete, sand, gravel, and water with the adequate metallic framework has made it possible to build solid and resistant structures for decades.
