Cemex goes global with carbon-neutral concrete
When it comes to construction, concrete is king, but making it releases a lot of carbon dioxide—about 8% of global emissions, acording to Chatham House policy institute. Demand for lower emissions is creating a market for concrete with a smaller carbon footprint, and the concrete maker Cemex is addressing the trend with what it calls the first globally available net-zero CO 2 concrete. Concrete packs a double wallop of CO 2 : manufacturers must use fuel to heat limestone to 1,300 °C; the conversion of CaCO 3 to CaO releases CO 2 as a by-product , explains Steven J. Davis, a professor of earth system science at the University of California, Irvine. They further heat the CaO to 1,450 °C to sinter it with other components, like gypsum, to form clinker, the cement that binds standard concrete together. Cemex’s Vertua Ultra replaces limestone-based clinker with an alumina-silicate polymer matrix activated
Success in Europe with inorganic polymeric binder leads to worldwide launch
