Description: Das Projekt "Novel remediation strategies for preservation of marble structures endagered from environmental damages" wird vom Umweltbundesamt gefördert und von Bayerisches Landesamt für Denkmalpflege durchgeführt. General Information: The objective of this project is to provide a set of rules for Good Marble Remediation Practice (GMRP) based on a multidisciplinary approach involving laboratory experiments in batch reactors and in climatic and salt spray chambers together with atmospheric exposure of various types of marble specimens both untreated and treated. The treatment of the marble specimens will be done both according to practiced approaches and with novel methods such as the adsorption of marble dissolution inhibitors and retardants of the growth of gypsum. Moreover novel remediation methods based on the deposition of calcium carbonate will be employed on the marble specimens. The approach to be followed will be based on model fundamental studies of the dissolution of calcium carbonate polymorphs and marble powders in batch reactors at various conditions of temperature, pH, under saturation and fluid dynamics. The kinetics measured will be formulated into a law describing the marble dissolution process. This law will provide the possibility of rapid testing of water soluble protective additives. Moreover, extension of the model experiments to marble slabs designed so that their shape will be representative of the mode of atmospheric exposure of the monuments, will be exposed under carefully controlled conditions in climatic salt spray chambers and in the atmosphere, at selected sites representative of the climatic conditions encountered in Europe. The kinetics results obtained from all experiments on the basis of physical, chemical and biological parameters of the marble undergoing weathering will be combined into a predictive mathematical model describing marble weathering. The methodology to be followed is anticipated to lead to the evaluation of the effect of atmospheric parameters on marble deterioration and the relative evaluation of marble treatment practices. Prime Contractor: Foundation of Research and Technology - Hellas, Institute of Chemical Engineering and High Temperature Chemical Processes; Patras; Greece.
