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.

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

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.

Researchers injected CO2 gas into seawater while applying an electrical current. The process transformed dissolved ions, minerals in seawater into clusters of solid particles. The clusters hold over ...

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

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 ...

"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 ...

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 ...

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

Luton, Bedfordshire, United Kingdom, March 31, 2025 (GLOBE NEWSWIRE) -- The global calcium carbonate plastic filler market is projected to reach approximately $25 billion by 2034, growing from an ...
