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.

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.

While traditional cement production gets its necessary calcium carbonate from limestone that releases carbon dioxide when heated in a kiln, the U-M researchers can make the calcium carbonate ...

By replacing fossil-fuel-driven calcination with electric heating, the ECem project aims to revolutionize cement production, reducing CO2 emissions while improving efficiency. The cement industry is ...

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

The market is predominantly driven by the increasing product utilization in several applications such as paper, plastics, and concrete manufacturing. The growing demand from the rubber industry for ...

The architectural mortar samples were collected from the bordering concrete city wall (C). Large-area EDS mapping of a fracture surface (D) reveals the calcium-rich (red), aluminum-rich (blue ...

The rare wildflowers grow only on soils containing calcium carbonate, which is used in medicines, toothpaste, cement and other products. “This mining withdrawal is a key step in protecting these ...
