Dear Colleagues,
We are pleased to invite you to the scientific session "The role of mineralogical sciences in the development of sustainable cement-based materials" to be held at the 21st General Meeting of the International Mineralogical Association (IMA 2014, Sandton Convention Centre, Gauteng, South Africa, 1-5 September 2014) organized by:
Gilberto Artioli (Dept. of Geosciences - University of Padua)
Andreas Luttge (MARUM - University of Bremen)
Luca Valentini(Dept. of Geosciences - University of Padua)
Joe Biernacki(Dept. of Chemical Engineering -- Tennessee Technological University)
The aim of the session is the dissemination of recent achievements in the study of both traditional and alternative "green" cement binders, obtained by experimental and numerical approaches.
A keynote presentation on the state of the art and current applications of "eco-friendly" cement will be delivered by Prof. Jannie van Deventer (Zeobond Group & University of Melbourne).
Oral and poster contributions covering the above subjects are welcome (deadline for abstract submission 28 February 2014).

Session description:
Binders and cements are crucial materials in modern human activities.
Advanced mineralogical techniques and computational models may provide important information for linking the molecular, microstructural, kinetic and thermodynamic information required to understand and control the behaviour of such materials during the hydration process, and their use in practical applications. Critical problems involved in the development of modern sustainable cementitious materials include the global generation of CO2 during mass production of Portland clinkers, the use of recycled materials, and the development of alternative, durable and environmentally-compatible cements. Some of the key themes are for example (a) the understanding of the hydration kinetics and microstructure development in conventional cement binders, (b) the nanostructural nature of the calcium silicate hydrates phase formed during hydration, (c) the crystal structure complexity of C-S-H and other cement-related minerals, (d) the role of secondary cementitious materials obtained from industrial and agricultural wastes in the production of blended cements; (e) the mechanisms of reaction and performance of alkali-activated cements (geopolymers).
