EPFL, the Indian Institute of Technology (IIT) in Delhi and Development Alternatives work toghether with the Cuban University of las Villas (UCLV) to develop new type of cements that can be produced by replacing part of the clinker (material produced in cement kiln) with a combination of calcined clay and limestone. Overall reductions of up to 50% in associated CO2 emissions are possible. The practical and scientific feasibility of these new materials needs to be well demonstrated for the technology to be adopted by the industry and users from large to small scale production.
