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.
