Summary and presentations of the conference on natural plasters and cement of 21/05/15 at the Marseille History Museum
Since 2003, the Vicat Group has been a member of the French Heritage Partners Circle, and three research programmes have been carried out under this partnership with the purpose of gaining a better understanding of the natural cement heritage. The first two addressed in particular the use of natural cement from the 19th century onwards in the Rhône-Alpes region. The third programme, the results of which were given during the symposium, focused on the natural cement heritage of Marseille. These latter efforts, carried out locally in collaboration with the Interdisciplinary Centre for Heritage Conservation and Restoration (CICRP), have enhanced our knowledge of the history of the development of this material in the Marseille context, of the typologies of buildings and of the recurrent pathologies, and have yielded important information on the physico-chemical and micro-structural properties of these materials.
