CEMROC®

Low-CO₂ Emissions

CEMROC®, just one of a growing range of eco-efficient products offered by Holcim, offers very low CO₂ emissions in production.
.

CEMROC® is produced by adding extra components to a slag cement, which enhances the properties of the end-product concrete and makes it resistant to aggressive environmental conditions. In comparison with conventional concrete, concrete made with CEMROC® is more resistant to a range of chemicals and offers exemplary durability and service life.

The production of CEMROC® generates around 95 percent less CO2 than traditional Portland cement. Promising applications include concrete elements prefabricated under industrial conditions, as well as bridges, dams and components for sea defenses and port facilities.

The main driver for reducing CO₂ emissions comes from substituting clinker in cement with appropriate secondary materials. Holcim now has one of the lowest clinker factors in the industry. We offer customers made-to-measure, application-specific solutions using composite cements, containing mineral components such as slag or fly ash in addition to clinker and gypsum. These comprise 75% of the cement types produced by Holcim.
