Prof. Admir Masic speaks with NPR host Scott Simon about the concrete blend used by the ancient Romans to build long standing infrastructures. “We found that there are key ingredients in ancient Roman concrete that lead to a really outstanding functionality property in the ancient mortar, which is self-healing,” explains Masic.
Reuters reporter Will Dunham writes that a new study by MIT researchers uncovers the secret ingredient that made ancient Roman concrete so durable and could “pave the way for the modern use of a replicated version of this ancient marvel.” Prof. Admir Masic explains that the findings are “an important next step in improving the sustainability of modern concretes through a Roman-inspired strategy.”
MIT researchers have discovered that ancient Romans used lime clasts when manufacturing concrete, giving the material self-healing properties, reports Katie Hunt for CNN. "Concrete allowed the Romans to have an architectural revolution," explains Prof. Admir Masic. "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."
Scientists from MIT and other institutions have uncovered an ingredient called quicklime used in ancient Roman techniques for manufacturing concrete that may have given the material self-healing properties, reports Jacklin Kwan for Science Magazine. When the researchers made their own Roman concrete and tested to see how it handled cracks, “the lime lumps dissolved and recrystallized, effectively filling in the cracks and keeping the concrete strong,” Kwan explains.
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.
Wired reporter Matt Simon spotlights a study by researchers from MIT and other institutions that finds smartphones in cars could be used to track the structural integrity of bridges. The findings “could pave the way (sorry) for a future in which thousands of phones going back and forth across a bridge could collectively measure the span’s health, alerting inspectors to problems before they’re visible to the human eye,” writes Simon.
Principal Research Scientist Randolph Kirchain, co-director of the Concrete Sustainability Hub, speaks with Jane Margolies of The New York Times about how the Inflation Reduction Act expands eligibility for tax credits for installing emissions-reduction equipment at manufacturing plants. “These credits are really valuable to keep technology coming down in cost,” says Kirchain.
Prof. Craig Steven Wilder is a featured expert in a new documentary titled “Driving While Black: Race, Space and Mobility in America,” reports WBUR. “For me, the term ‘driving while black’ isn’t just a slogan, it isn’t just a part of our political rhetoric, it’s not just something we say to remind ourselves of the persistence of racism in the United States. It’s a very personal experience of remembering, in fact, the anxiety, the fear,” says Wilder.
Prof. Karilyn Crockett speaks with Boston Globe reporter Miles Howard about how transportation planning in the Greater Boston area needs to be centered around improving connectivity. “As Boston’s population grows, our public transportation infrastructure continues to crumble, and our transit planning can’t just be about new cars on one line and new tracks on another,” says Crockett. “It has to be a discussion about the system and the economic impacts of that system on Black and brown communities that are struggling to get to doctors’ appointments, to schools, to jobs that don’t allow working from home.”
MIT startup ReadySet, co-founded by Alana Marzoev PhD ’18 and Jon Gjengset PhD ’20, provides database infrastructure to help developers build real-time applications, reports Kyle Wiggers for TechCrunch. “Rather than rebuilding these same broken systems, developers need solutions that slot into their existing infrastructure and achieve limitless read scaling,” says Marzoev. “With ReadySet, we aim to make the process of globally caching… query results as streamlined and automated as caching images in a content delivery system.”
Prof. Mariana Arcaya writes for The Boston Globe about how the Bipartisan Infrastructure Investment and Jobs Act, and the Build Beck Better bill will help combat the ongoing global climate crisis. “Shifting away from fossil-fuel consumption and combatting injustice are the two keys to solving the climate crisis,” writes Arcaya. “The Bipartisan Infrastructure Act provides vital funding for some of the measures the United States needs to take.”
Favelas 4D, an MIT Senseable City Lab project, uses 3D laser scanning technology to produce digital maps of Rio de Janeiro’s favelas to help build infrastructure that benefits local communities. “A digital map can benefit crucial delivery systems like medical supplies and mail, as well as improve waste and water collection for favela residents,” writes Teodosia Dobriyanova for Mashable.
Prof. Carlo Ratti has proposed a 51-story skyscraper for China’s technology hub of Shenzhen that would produce crops to feed populations of up to 40,000 per year, reports Bloomberg News. “Ratti envisions his farmscraper as a self-contained food supply chain, where the crops can be cultivated, sold and eaten all within the same building.”
