ENVIRONMENTAL IMPACTS OF CEMENT PRODUCTION

The cement industry has made significant progress in reducing CO2 emissions through improvements in process and efficiency, but further improvements are limited because CO2 production is inherent to the basic process of calcinating limestone . Life cycle assessment (LCA) is used to evaluate the impact of processes or products on the environment.

UCLA scientists confirm New technique could make cement

During cement manufacturing, there are two steps responsible for carbon emissions. One is calcination, when limestone, the raw material most used to produce cement, is heated to about 750 degrees Celsius. That process separates limestone into a corrosive, unstable solid — calcium oxide, or lime — and carbon dioxide gas.

and is the newer term to be used for both Portland Cement and Blended Cement. The invention of Portland Cement is credited to Joseph Aspdin, an English mason, in 1824. He named his product Portland Cement, because it produced a concrete which resembled a natural limestone quarried on the Isle of Portland.
