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

A new technique can produce cement using waste from demolished buildings, which researchers say could save billions of tonnes of carbon by 2050. “We have definitely proved that cement can be recycled ...

One September day, it started to snow inside MIT's Pierce Laboratory. Researchers depressurized a tank of liquid carbon dioxide (CO2), instantly freezing it and releasing solid flakes. These were ...

Cement is necessary for making concrete, which is foundational in constructing buildings and infrastructure around the globe because it is relatively low-cost, strong and durable. But making cement ...

Researchers have developed a method to produce very low emission concrete at scale -- an innovation that could be transformative in the transition to net zero. The method, which the researchers say is ...

Norway’s Statoil saves hundreds of millions of euro in avoided carbon taxes by using CCS. Since 1996, the Sleipner gas field has stored about one million tonnes CO2 a year. A second project in the ...

For true zero carbon cement, the process can draw pure calcium from impurities in silica, magnesium, iron or aluminum, for example, refining them into higher-grade materials in the process. Crucially, ...

Not only could the new process help sequester CO 2 from the ever-warming atmosphere, it also results in concrete with uncompromised strength and durability. “More interestingly, this approach to ...

If you find yourself at this moment in a city of any size, take a look out the window. Most of what you see is made with a single material, one that dominates our world: concrete. It makes up the bulk ...
