The manufacturing of Portland cement results in emission of large quantities of Carbon Dioxide (CO2). Every ton of Portland cement produced creates almost 1 ton of CO2 released to the atmosphere.


Cement is made by heating limestone and other materials to a temperature of 2700 degrees (F) to produce "clinker", then grinding the clinker to a fine powder.

CO2 is produced by the burning of fossil fuels to generate the heat and also by the chemical reaction of the limestone, converting Calcium Carbonate (CaCO3) to Calcium Oxide (CaO). 

CaCO3 à CaO + CO2

Geofortis SCM products directly replace Portland cement in concrete.  Using Geofortis products allows concrete producers to meet specifications for green buildings and reduce impacts on climate change.
