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

Producing cement from silicate rocks rather than limestone could lower both energy requirements and carbon dioxide emissions, ...

Cement production alone currently accounts for about 8 percent of global CO 2 emissions, so considerable effort is going into ...

Salt X Technology AB and Holcim have, within the framework of their joint development collaboration, successfully and ...

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

This process can't avoid producing CO2 – but at least it comes out in a pure, cold state, pre-compressed to 10 bar and ready for easy capture and storage – and using substantially less energy and ...

For decades, the key metrics for concrete in construction were durability, reliability, safety and cost. In recent years, however, sustainability has been added to that list by customers seeking to ...

A new study suggests that using basalt rock instead of limestone in cement production could significantly reduce carbon ...

Researchers from the University of Michigan, Lawrence Livermore National Laboratory, Northwestern University and the California Institute of Technology recently developed a new cement manufacturing ...

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 ...
