Fast Company reporter Adele Peters writes that researchers from MIT and other institutions have found that a technique employed by ancient Romans for manufacturing concrete contains self-healing properties and could be used to help reduce concrete’s global carbon footprint. The ancient concrete method could open the “opportunity to build infrastructure that is self-healing infrastructure,” explains Prof. Admir Masic.
Researchers at MIT and elsewhere have found that using ancient Roman techniques for creating concrete could be used to create buildings with longer lifespans, reports Nicola Davis for The Guardian. “Roman-inspired approaches, based for example on hot mixing, might be a cost-effective way to make our infrastructure last longer through the self-healing mechanisms we illustrate in this study,” says Prof. Admir Masic.
Researchers at MIT have found that applying ancient Roman techniques for developing concrete could be used to reduce concrete manufacturing emissions, reports Saul Elbein for The Hill. “Researchers said blocks treated with the method — in which concrete was mixed with reactive quicklime under continuous heat — knit themselves back together within a few weeks after being fractured,” writes Elbein.
Junior Madison Douglas speaks with Boston Globe reporter Marvin Pave about the many activities she is involved in at MIT, including researching volcanic activity in Spain, playing flute in the orchestra and serving as the women’s sabre squad leader. “I really enjoy everything I do, but at the same time I have to be disciplined and maintain a balance,” says Douglas.
Dr. David Ridley of MIT is leading a new effort to study the amount of volcanic particles at high altitudes and how these particles might have contributed to a pause in global warming . Ridley and his team found a “high enough level of particles to account for a global cooling of 0.05–0.12 °C since 2000,” Nature reports.
The Christian Science Monitor’s Peter Spotts reports on new MIT research that finds volcanoes may be the cause of a recent hiatus in the rise of global surface temperatures.
