The lifespan of a building can vary greatly depending on a number of factors, including the quality of its construction, the materials used, the climate in which it is located, and how well it is maintained. Some buildings can last for hundreds of years, while others may only last for a few decades. Factors that can affect the lifespan of a building include the type of foundation, the type of roof, the type of walls, and the type of windows.
In general, buildings with good-quality materials and construction tend to last longer than those with lower-quality materials and construction. Proper maintenance, such as regular inspections, repairs, and renovations, can also help to extend the lifespan of a building.
However, Roman buildings have lasted for millennia, exceeding all expectations. Scientists finally have an answer to the mystery.
It all lies in the quality of Roman concrete
A new study that CNN reveals has found that Roman concrete, which is still standing after thousands of years, is more durable than modern concrete, which can deteriorate within decades. The researchers discovered that the durability of Roman concrete is due to the inclusion of white chunks, known as lime clasts, which allow the material to heal cracks that form over time. The findings could potentially lead to the development of more durable modern concrete.
Researchers from the United States, Switzerland, and Italy studied 2,000-year-old concrete samples taken from a city wall at the Privernum archaeological site in Italy, which are representative of concrete used throughout the Roman Empire.
Admir Masic, the author of the new study and also an associate professor at the Massachusetts Institute of Technology, stated as CNN quotes:
Concrete allowed the Romans to have an architectural revolution,
Romans were able to create and turn the cities into something that is extraordinary and beautiful to live in. And that revolution basically changed completely the way humans live.
Some of the most visited Roman buildings today include the Colosseum in Rome, the Pantheon in Rome, the Roman Forum in Rome, Pompeii in the region of Campania, and Hadrian’s Wall in northern England. The Colosseum is a well-preserved ancient building that was used for gladiator games and other public spectacles. The Pantheon is a temple dedicated to the gods of ancient Rome and is known for its impressive dome with an oculus at the top.
