Sažetak
The aim of this work is to evaluate the consolidation performance on different types of Croatian limestones that were used for monuments in the past. The fresh quarry samples have been consolidated with Particle Modified Consolidants (PMC) consisted of a silicate matrix (Conservare OH-100) and colloidal alumina particles (Al2O3). This composite has been chosen on the basis of a bibliographic research aimed to better protection from salt crystallization damage [1]. The application by capillary rise has been taken under laboratory conditions [2]. Different stone types show different behaviours towards consolidation. Knowledge of consolidant distribution within the porous stones is important in definition of more appropriate consolidant for each particular case. The evaluation of consolidation effect in the samples has been carried out by the study of the depth profiles and elemental distribution of silicon and aluminium. Analysis was performed by external beam millibeam as well as with in vacuum microbeam PIXE spectroscopy. Additionally, the modification of the stone structure induced by consolidation treatment has been examined by optical and electronic microscopy. The differences between fresh and strengthen stone samples are discussed. The results obtained in this investigation are significant because of their contribution to better understanding of consolidation process in the stone.
