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

The production process for cement requires grinding and heating limestone in industrial kilns at temperatures as high as 2,800° F. That creates “clinker,” which is the base element of most types of ...

Research reveals basalt-derived calcium can cut Portland cement emissions, reduce energy use by 30%, and produce valuable ...

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 ...

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 ...
