Aether®, new generation clinker

Lafarge has successfully completed an industrial trial for Aether®, its new generation clinker formulated for lower carbon cements. The trial mobilised a team of around a hundred people over a ten -day period at the Group's plant in Le Teil, France. It allowed the production of 10,000 tonne of Aether® clinker, confirming the feasibility of industrial-scale production using traditional raw materials. The launch of the first Aether® products is planned for 2014.The result of several years of research by Lafarge R&D teams; Aether® is a new generation clinker, the basic component of cement. Aether® cements offer similar properties to ordinary Portland cement and can be produced in traditional cement plants after minor process adjustments, for a lower overall environmental footprint. Aether® is a new chemical composition for clinker which should allow a 25 to 30 per cent reduction in CO2 emissions, thanks to reduced limestone content in the raw mix, a lower temperature (1300°C) during the burning process, and easier grinding, using less energy. This development project has received the support of the European Union as part of its LIFE+Programme, a financial instrument to support environmental projects. Lafarge has been working to reduce its CO2 emissions for over 20 years, using alternative fuels, cementitious additives and improving energy efficiency at its plants.
