MIT Scientists Create Greener, Stronger Concrete With Half the CO2 Emissions

MIT Scientists Create Greener, Stronger Concrete With Half the CO2 Emissions

MIT’s team of scientists led by senior research scientist Roland Pellenq, professors Krystyn Van Vliet, Franz-Josef Ulm, Sidney Yip, and Markus Buehle, found that changing the commonly used calcium-to-silica ratio of 1.7 to 1.5, produces a material two times the resistance of normal cement, in mechanical resistance to fracture. Besides improving mechanical strength of the material, this would also ensure “no residual stresses in the material”, which means the new type of cement would be more
