The diagrams illustrate the way in which cement is made and how it is then used in the process of making concrete.Overall,limestone and clay pass through four stages before being bagged ready for use ...

Even when there is a strong driving force for cement decarbonization, it is very challenging to lower the carbon footprint of the underlying cement-making process. The high temperatures required are ...

Researchers have created a low-lead method to convert CO₂ into solid metal oxalates. Researchers at the University of ...

That has allowed Prometheus Materials, a firm in Colorado, to develop a cement-making process in which the energy comes not from heat but light—something easily generated from electricity that ...

There are two major reasons why cement is such a climate nightmare. The first one is that the process of making it usually involves ridiculously high temperatures, around 1,400 °C. Getting to ...

Allwood and his colleagues have developed an alternative process to make clinker, which involves reusing cement paste from demolished buildings. This paste has an identical chemical composition to ...

cement, plaster and paint. The process to generate the carbon-negative materials also releases hydrogen gas — a clean fuel with various applications, including transportation. The study was published ...

But cutting down on those emissions is hard to do. Most of the carbon generated through cement making comes from the fundamental process of heating ground limestone (calcium carbonate), clay and ...
