Opis

NMR spectroscopy has become one of the most powerful methods for the study of the structure and dynamics of solid-state materials. NMR has thus become an important tool, not only in the study of existent cements, but also in the development of new cement-based materials. This volume, based on the proceedings of the second international conference on the NMR Spectroscopy of Cement Based Materials held in Bergamo, Italy, in June 1996, presents the only international overview of the state of the art in the use of NMR in the study of cement-based materials. - This book is of particular interest to all those working in the areas of cement science, material science, solid state chemsitry, analytical chemistry, spectroscopy and those areas of physics engaged in the study of materials.
