LC³ is a new type of cement that is based on a blend of limestone and calcined clay. LC³ can reduce CO2 emissions by up to 40%, is made using limestone and low-grade clays which are available in abundant quantities, is cost effective and does not require capital intensive modifications to existing cement plants.

The objective of the LC³-Project is, through research and testing, to make LC³ a standard and mainstream general-use cement in the global cement market.

The main research activities focus not only on specific thematic areas of cement research but also on production, environmental sustainability and cost effectiveness of this new cement.

With funding from the Swiss Agency for Development and Cooperation through its Global Programme in Climate Change, the has been able to bring the idea of the LC3-technology from the lab in Switzerland to all parts of the world.
