Abstract[edit]
The Karadjordje’s gate is a monument of culture, part of the historical complex of the Belgrade Fortress. The gate, dated from 1740 to 1791, is made of autochthonous limestone of Miocene age. After years of exposure to environmental conditions and different anthropogenic influences, the stone blocks showed a wide range of decay forms. The gate was subject to a restoration campaign in 2007 using cement based materials. Today, the gate shows renewed signs of degradation: detachment of “artificial stone” used for restoration; scaling and disaggregation of the original stone blocks. Salts efflorescence is present around the joints of stone blocks in the upper part of the gate and under the reconstructed rosettes. Characterization of salts was carried out by SEM-EDS and XRPD analyses. Results showed the presence of the following salts: syngenite, gypsum, thenardite, darapskite, bassanite, niter, aphthitalite and witzkeite. The paper concludes that there is an influence of restoration materials to salt contamination and to the decay of stone and “artificial stone”.
