Lafarge lower carbon cements

Listen

All around the world, Lafarge offers ranges of cements with lower CO2 emissions compared with traditional cements. These multi-component cements contain less clinker, whose production is responsible for a large proportion of cement's carbon footprint. As a substitute, they incorporate by-products from other industries, such as slag from steel production or fly ash from coal-fired power plants.

Lafarge lower carbon cements also have high mechanical performances, often combined with specific workability qualities. When incorporated into concretes, they improve their long-term resistance compared with that of traditional concretes.

They can be used in all types of constructions and infrastructure including large structures with very specific requirements, such as:

stadiums
bridges & footbridges
dams
skyscrapers

Project Aether

This project, presented in 2010, involves the development of a new class of lower-carbon clinkers for cement, using less limestone, manufactured at lower temperatures and consuming less energy than traditional Portland cement.

This allows a 25% to 30% reduction in CO2 emissions during manufacturing, for similar performance to Portland cement. Project Aether has received support from the European Commission as part of the LIFE+ environmental funding program.
