American researchers have developed a new method for capturing CO2 with its subsequent transformation into metal oxalates, which can be used as precur ...

The chemistry of cement and concrete is fascinating, there’s a process which uses supercritical CO2 to cure concrete and form a material that, if I remember and understood correctly, rapidly ...

Omaha’s roads are slowly killing themselves, self-destructing because of a hard-to-stop chemical reaction caused by the rock used in Nebraska's concrete.

Cement releases CO 2 from the chemical reaction that forms it and the fossil fuels that are used to provide heat to drive the reaction. One ton of cement produced in the U.S. releases about 0.8 ...

Concrete is made by mixing sand, cement and water. Concrete cancer, formally known as alkali-silica reaction, or ASR, causes concrete to swell internally and to crack when it comes in contact with ...
