2011 Percival Allen Medal Award, Corina Ionescu, Tudor Berza

Studia UBB Geologia

The Association of European Geological Societies (AEGS) connects geological societies all over Europe. In 2006, the AEGS Executive Committee established an award named for Prof. Percival Allen FRS, one of the AEGS's founders. This medal is given biennially to a geoscientist for outstanding achievements in the field of international relations in Earth Sciences. Other than a distinguished record in fostering international relations in geosciences, there are no special eligibility criteria. The Award Committee announces the laureate at the Meetings of AEGS (MAEGS).

Dr. Jens Dieter Becker-Platen from Germany (at MAEGS-15, held in Tallinn 2007) and Dr. Eduardo de Mulder from …

Experimental Techniques For Cement Hydration Studies, Andreas Luttge

Studia UBB Geologia

Cement hydration kinetics is a complex problem of dissolution, nucleation and growth that is still not well understood, particularly in a quantitative way. While cement systems are unique in certain aspects they are also comparable to natural mineral systems. Therefore, geochemistry and particularly the study of mineral dissolution and growth may be able to provide insight and methods that can be utilized in cement hydration research. Here, we review mainly what is not known or what is currently used and applied in a problematic way. Examples are the typical Avrami approach, the application of Transition State Theory (TST) to overall …
