Cement’s Magic Number
Concrete is the world’s most-used construction material, but it comes with the drawback that its production accounts for about 10% of global industrial CO2 emissions. An international research team sponsored in part by the cement industry and led by MIT’s Roland J.-M. Pellenq has used a computational molecular model for evaluating cement hydrate—the CaO-SiO2-H2O mineral binding phase in concrete—to help overcome the problem. The researchers found that adjusting . . .
