MIT Developing Concrete That Lasts for 16,000 Years

Civil engineers at MIT are currently developing a new breed of concrete that will be able to last for 16,000 years. Concrete is one of the most frequently used and widely produced man-made building material on earth, with over 20 billion tons produced per year globally.

The use of this new ultra high density concrete will have enormous environmental implications, given its ability to deliver lighter, stronger structures capable of lasting many civilizations, while drastically decreasing the carbon emissions sent into the atmosphere by its inferior predecessor.

One of the inventors of the new material, Franz-Josef Ulm offers, “More durable concrete means that less building material and less frequent renovations will be required.” Ulm, alongside Georgios Constantinides successfully designed this long lasting concrete, with significantly reduced creep, (the time-dependent deformation of structural concrete), by increasing its density and slowing its creep by a rate of 2.6.

“The thinner the structure, the more sensitive it is to creep, so up until now, we have been unable to build large-scale lightweight, durable concrete structures,” said Ulm. “With this new understanding of concrete, we could produce filigree: light, elegant, strong structures that will require far less material.”
