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 ...

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 ...

A University of Nebraska-Lincoln research team has identified new microscopic players in the global carbon cycle, a discovery ...

Potassium carbonate is one of the chemicals ... It generated enough heat for our purposes, and involved chemicals (water, calcium oxide and calcium hydroxide) that are comparatively safe and ...

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 ...
