Low-Carbon Concrete Can Fight Global Warming - ASME

18/02/2020  Low-Carbon Concrete Can Fight Global Warming Feb 18, 2020. by R.P. Siegel There’s likely not a more flexible material than concrete. That’s not a measure of its elasticity—when concrete sets, it’s as hard as rock—but of its uses. Concrete is found all over the modern world, from the swooping rooflines of the TWA Terminal at John F. Kennedy Airport in New York to the uninspiring ...

Low carbon concrete

Low embodied carbon constituents. Concrete is a low carbon material. Its versatility, performance and local availability has resulted in it being the second most consumed material globally (after water). The potential to reduce global carbon emissions, by reducing the embodied carbon of such a widely used material are not in doubt.
