Portland cement has an adverse impact on the environment. The cement industry produces approximately 5% of all global man-made CO2 emissions. Half of these emissions are from chemicals processed during the production of Portland cement while the other half come from burning fuel in high temperature kilns. The first step in the manufacture of Portland cement involves the cracking of limestone in high temperature kilns, a process that releases a huge amount of carbon dioxide. Producing one ton of Portland cement generates one ton of CO2 emissions.
The production of Reco Cement’s additives generates minimal CO2 emissions because they are dry-mixed and do not require the use of kilns. Construction contractors reduce their carbon dioxide emissions on pound-for-pound basis by using Reco Cement’s additives and fly ash (or granulated slag), which serve as a volume replacement for Portland cement.
