With cement significantly contributing to the embodied carbon from construction, new green cement solutions could enable ...

Together with a team they developed a method to combine old concrete with carbon dioxide, taken from the air or industrial exhaust, to create a new, durable material called calcium carbonate concrete.

For instance, one Oakland-based company is commercializing cement made from carbon-free calcium silicate rock, which emits no carbon dioxide when processed in a kiln. By combining clean heat with ...

To make concrete, limestone, or calcium carbonate, is mixed with clay and other materials and then calcined at high temperatures, so CO2 is released via the thermal decomposition of calcium carbonate.

Calcium carbonate (CaCO₃) is a naturally occurring compound found in various forms, including limestone, chalk, and marble. It serves as a critical raw material in multiple industries, such as ...

The term "green cement" is still relatively new, but a Cape Breton economic development group feels the Strait of Canso could be the newest home for carbon-removal technologies that have already ...
