Carbonated Cement for Production of Concrete with Improved Properties

NASA’s Marshall Space Flight Center has developed a new cement composition and manufacturing method that enables carbon dioxide (CO2) emissions reduction in cement manufacturing while also providing a cement with improved performance capabilities. Building off of expertise in life-support oxygen-control systems for spacecraft, researchers have demonstrated a process whereby carbon is reduced to solid form from captured CO2 emissions and becomes an inherent component of the cement product. The technical viability of the innovation was demonstrated with laboratory testing indicating that, in addition to reduced CO2 emissions, cement compositions with enhanced properties can be attained.
