Ideas to reduce carbon emissions often revolve around renewable power, electric vehicles and energy efficiency. But there's another, less colorful character that's often overlooked: cement.

Cement production alone currently accounts for about 8 percent of global CO 2 emissions, so considerable effort is going into lowering that number. Efficiency can be increased, and energy sources can ...

Scientists are proposing a new way to make cement by replacing limestone with volcanic ...

Cement is known for producing a significant amount of carbon emissions that pose a threat to the environment. That, however, could change following a unique discovery involving ancient times. Tiziana ...

Spontaneous carbonation The new approach was inspired by a centuries-old technique for making cement. Cement production begins by converting limestone to calcium oxide in a kiln heated to about 1,400 ...

Cement production creates nearly as much CO2 as passenger cars, but replacing limestone with basalt could cut emissions by up to 80 percent.

A new process could enable crushed rocks to capture carbon dioxide from the air much more quickly, turbocharging a carbon removal technique that is already being widely adopted. Natural silicate ...

This strange white paste might not look like much, but it might help solve the sand shortage, while making the cement manufacturing process capture carbon dioxide instead of emitting it. Scientists at ...

Concrete is all around you—in the foundation of your home, the bridges you drive over, the sidewalks and buildings of cities. It is often described as the second-most used material by volume on Earth ...
