Cities of the future may be built with locally available volcanic ash

07.02.2018 | MIT | news.mit.edu

MIT engineers working with scientists in Kuwait have found that volcanic rocks, when pulverized into a fine ash, can be used as a sustainable additive in concrete structures.

In a paper published online in the Journal of Cleaner Production, the researchers report that, by replacing a certain percentage of traditional cement with volcanic ash, they can reduce a concrete structure’s “embodied energy,” or the total energy that goes into making concrete.

Cities of future

According to their calculations, it takes 16 percent less energy to construct a pilot neighborhood with 26 concrete buildings made with 50 percent volcanic ash, compared with the energy it takes to make the same structures entirely of traditional Portland cement.
