In a letter to The Guardian, Prof. Franz-Josef Ulm, Randolph Kirchain and Jeremy Gregory of the Concrete Sustainability Hub argue that “concrete remains a vital means of social and economic transformation for developing nations.” The authors add that “we ought to expand our understanding of it and use its full potential to enable sustainable development.”
Jeremy Gregory, executive director of the MIT Concrete Sustainability Hub, writes for USA Today about how the quality and condition of a roadway impacts a vehicle’s fuel use and greenhouse gas emissions. “Actions that improve road design and conditions can reduce vehicle fuel consumption and emissions,” argues Gregory.
In an article for The Huffington Post, Erik Rancatore highlights how “researchers at the MIT Concrete Sustainability Hub have developed a method to incorporate the risk and repair costs of damage from hurricanes and earthquakes into life-cycle analysis of residential buildings.”
Johanna Knapschaefer writes for ENR that MIT researchers have developed a new pavement-vehicle interaction test to measure the amount of fuel saved from driving on repaved highways. “For each road, we know the amount of traffic, the temperature [of the pavement], structural data, material data and GPS coordinates,” explains Prof. Franz-Joseph Ulm.
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.
New York Times reporter Colin Nickerson writes about Professor Linn Hobbs’ research into whether the ancient Egyptians used a synthetic material to build the Great Pyramids. "It could be they used less sweat and more smarts," Hobbs told The New York Times.
