Hormigón y mortero de albañilería con miles de años de antigüedad, siguiendo el ejemplo de los antiguos constructores
Ancient buildings from the Roman era seem to be built for eternity. It is obviously a very special building material.
The Pantheon is one of the most famous buildings of ancient Rome, still defying the elements after almost 2000 years. Just as old, numerous amphitheatres such as the Colosseum, huge aqueducts and port facilities still stand today. The sturdy, millennium-old buildings of the Romans can also be found in Spain, Greece and Turkey. Modern concrete buildings, on the other hand, only last 100 years, while our motorways and bridges have only lasted 50 years.
While modern concrete is mixed in such a way that chemical changes are suppressed, the Romans relied on the opposite. The difference was not only in the high-performance "Opus Caementicium" (ancient Roman cement), which even below ground still holds together the water or sewage supply of Mediterranean cities today. There are other ingredients that account for the stability of the ancient buildings. The different forms of lime (burnt or slaked), as well as the use of lime that has been sumped for years, also make this possible.
But these buildings are not only relevant from a historical and aesthetic point of view. Roman concrete could also contribute to reducing today's CO2 emissions.
