Latest Invention: New Concrete Developed to Last for 16,000 Years

Share

Engineers at Massachusetts Institute of Technology are now developing a new type of concrete. They claim their latest invention will be able to last for not less than 16,000 years. For statistics: each year 20 billion tons of concrete are produced worldwide.

The new concrete boasts ultra high density. With its help engineers will be able to build lighter and stronger structures that would stand still throughout many civilizations, while considerably reducing carbon emissions sent into the atmosphere. In addition, the more durable a concrete is, the less building material will be required and thus fewer renovations will be needed.

Franz-Josef Ulm and Georgios Constantinides are two engineers who worked on the latest invention, which they say has a considerably reduced creep (the time-dependent deformation of structural concrete).

"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. With this new understanding of concrete, we could produce filigree: light, elegant, strong structures that will require far less material," explains Ulm.

It is worth mentioning that the production of concrete generates between 5 and 10 percent of all atmospheric carbon dioxide. Ulm says that the production of new, stronger and lighter concrete would reduce the carbon emission by 1/7. More about the latest invention can be found at MIT.edu
