The concrete industry accounts for roughly 8 percent of global carbon dioxide emissions, but a new study says that it could ...

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.

With a composition of half calcium carbonate and half magnesium hydroxide, for example, 1 metric ton of the material has the capacity to store over one-half a metric ton of CO 2. Loria also says the ...

Researchers have made a groundbreaking paste that could help create carbon-capturing concrete in new construction projects.

With a composition of half calcium carbonate and half magnesium hydroxide, for example, 1 metric ton of the material has the capacity to store over one-half a metric ton of CO 2. Rotta Loria also says ...

The quest for carbon-neutral concrete has become a billion-dollar endeavor – but a team of scientists from Northwestern gas gone one better.

"Cement, concrete, paint and plasters are customarily ... The reaction produced solid minerals, including calcium carbonate and magnesium hydroxide. Calcium carbonate directly acts as a carbon ...

Living concrete represents a revolutionary advancement in construction materials, merging biology and engineering to create self-healing components that repair damage autonomously. This ...
