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.
Writing for Metropolis, James McCown highlights the architecture of the new MIT buildings in Kendall Square, particularly the property at 314 Main Street, which houses the new MIT Press Bookstore and MIT Museum. “To walk across the campus of the Massachusetts Institute of Technology is to get a crash course in 20th and early 21st-century architecture,” writes McCown. “Who wouldn’t want to add their signature to this splendid architectural canvas?”
TechCrunch reporter Christine Hall spotlights Anwar Ghauche MS ’10, CEO of Constrafor - a construction procurement platform that streamlines information, payment, and documentation between general contractors and subcontractors. “Subcontractors get hired on the project, and when they finish their first month of work, submit an invoice and then wait an average of 45 to 60 days — even up to 80 days — to get paid,” says Ghauche. “Meanwhile, they are buying equipment and borrowing money to be able to do all of this work. You’re not borrowing at a cheap rate, either, because most banks barely touch them.”
Next spring, the Stratton Student Center is set to undergo significant renovations, which will include “refreshing the physical space inside and outside the building, launching the Wellbeing Lab, updating dining options, and upgrading the existing infrastructure,” reports Andrea Jaba for The Tech. “This project is all about putting MIT’s students at the center of our student center,” said Chancellor Melissa Nobles.
Boston Globe reporter Bryan Marquard memorializes the life of alumna Natalie Adelman Taub, known for her pioneering work in Boston’s construction field. “Why should construction be exclusively a man’s field?” said Taub in 1954, after founding her own firm. “There are many fine women architects, designers, and decorators, so why not women contractors?”
In this 3-minute read, Katharine Schwab of Co.Design highlights Assistant Prof. Brandon Clifford's project, Cyclopean Cannibalism. Updating an ancient building technique, "Clifford and his students have built algorithms that can...suggest a type of cyclopean wall design that would be able to transform any mound of debris into a wall," writes Schwab.
USA Today reporter Tracy Moran writes about the use of environmentally friendly materials in constructing buildings, highlighting Prof. Rolland Pellenq’s work to make concrete more sustainable. “His work has proven that reducing the ratio of certain materials can make concrete nearly twice as resistant to fractures while cutting concrete emissions by as much as half,” writes Moran.
David Weinberg of Marketplace reports that MIT researchers have developed a formula for concrete that reduces its greenhouse-gas emissions. Dr. Roland Pellenq explains that to make a “greener” cement, researchers examined concrete’s properties at the “sub-micron or big-nano level.”
Professor Rolland Pellenq’s team has developed a new formula that would reduce the greenhouse gas emissions associated with concrete production by half, reports Julia Pyper for Scientific American. The mixture also achieves "two times the resistance of normal cement, in mechanical resistance to fracture,” says Pellenq.
