Cemtech lIve Webinar - clinker reduction technologies

Advances in clinker reduction technologies
Calcined clays, new binder concepts and production technologies

This Cemtech Live Webinar explored clinker reduction opportunities in the cement manufacturing, one of the key levers in the cement industry’s sustainability pathway. Calcined clays, new binder concepts and production technologies were all reviewed with one of the industry’s most eminent cementitious materials experts, Professor Karen Scrivener, EPFL (Switzerland). FCT Combustion also considered the role of flash calciners in the production process, while thyssenkrupp Industrial Solutions detailed its polysius® activated clay solution.

Opportunities and challenges of manufacturing limestone calcined clay cement (LC3): Karen Scrivener, EPFL (Switzerland)
In 1995, Prof Karen Scrivener joined the Central Research Laboratories of Lafarge, near Lyon in France, as Head of Research on calcium aluminate cements and expert of concrete durability in general. In March 2001, she was appointed as Professor and Head of the Laboratory of Building Materials, Department of Materials, at the Swiss Federal Institute of Technology at Lausanne (EPFL, Ecole Polytechnique Fédérale de Lausanne), Switzerland.  She created and is co-ordinating NANOCEM – the industrial-academic research network on cement and concrete, which brings together 15 industrial and 24 academic partners.
