In their previous experiment, the team created calcium carbonate concrete by pouring a bicarbonate solution through carbonated concrete powder and heating it. In this updated version, as well as ...

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 ...

If a compound is heated it will break down to two or more substances and these can be elements or compounds. So, if we have calcium carbonate and we heat it, it breaks down to produce calcium ...

It is then shaped and compressed so the calcium carbonate particles bond and solidify. Heat is applied in the final stage to complete the process. The scientists discovered that the concrete ...

Construction is imminent for a carbon-capture project aimed at reducing CO2 emissions from steel production while producing carbon-neutral calcium carbonate. At the U.S. Steel manufacturing facility ...

In this study, the team engineered a new pesticide formulation that uses modified carbon dots and calcium carbonate particles as carriers for abamectin. This new formula enhances adhesion to ...
