ClimateWire: Concrete is the most-used construction material in the world and a major contributor to global greenhouse gas emissions. But by using a different chemical formula to make the material, new research suggests it’s possible to significantly reduce concrete’s carbon footprint.
Concrete has a complex molecular structure made of a mixture of sand, gravel, water and cement. The cement is made by heating a calcium-rich material, typically limestone, with a silica-rich material, typically clay, at temperatures…
