“…Recently, micro‐Raman spectroscopy, commonly used for the investigations of archaeological artefacts, organic and mineral painting pigments, ceramics and glasses, is more often applied to detecting the weathering products of the building materials . This method is one of the convenient analytical tools in the phase analysis of single particles, which allows also to distinguish among the hydration states of minerals (e.g.…”

Salts crystallisation is a cause of deterioration of stone monuments. Very small sizes of salt crystals, often a multiphase composition and usually low concentrations hamper their identification. Therefore, micro‐Raman spectroscopy, scanning electron microscopy and, in some cases, X‐ray diffraction have been used to identify the salts that crystallised within and on the weathered limestone and sandstone architectonic details of the Blessed Salomea sculpture and its arch in the cloister of the Poor Clares in Kraków, Poland. Possible sources of salts, i.e. regarding the plaster around the details, the mortar of joints of the arch and previous conservation procedures, have been discussed. The limestone sculpture reveals the presence of black crusts and the sandstone arch of white efflorescences, both stones crumble and exfoliate. Gypsum and barite were the only salts in the black crust and subflorescences of the limestone. The salts in the pore space of the sandstone include mainly aphthitalite, niter, nitratine and burkeite, while efflorescences consist of thenardite and syngenite. Such differences probably result from various precipitation conditions in narrow pore spaces and on the unconfined sandstone surface. The deterioration products have been mainly assigned to air pollution, stone itself in the case of the limestone, and migration of ions from structural elements of the arch in the case of the sandstone. The impact of the chemicals utilised for stone conservation also seems to be possible. Characterisation of the salts present in deteriorated stones can help in selecting the methods of stone desalination and conservation. Copyright © 2016 John Wiley & Sons, Ltd.

“…In fact, buildings might The trace elements composition (Table S3) plotted in Figure 5 emphasised a critical aspect: C&D waste samples commonly contain anomalously high concentrations of heavy elements (Co, Cr, Cu, Ni, Pb, V, and Zn), which are potentially hazardous for human health [18]. In fact, buildings might be repositories of pollutants of anthropogenic origin, including heavy metals [19]. Once building materials become C&D waste, they will be a potential source of contamination [20].…”

In the Republic of Macedonia, construction and demolition (C&D) waste is often dumped, underestimating the potential recycling and re-use as raw materials for civil engineering works and/or cement/ceramic industries. SAMCODE (Sustainable Approach to Managing Construction and Demolition Waste) is a know-how exchange program, the focus of which is chemical characterisation in terms of major and trace elements in order to evaluate the possible Macedonian C&D waste recycling. Thirty-nine C&D waste samples were collected from different dumps in Skopje and surroundings. X-ray fluorescence analyses, carried out on powdered samples, show i) highly variable concentrations, indicative of the heterogenous nature of C&D waste, and ii) high concentration in Cr, Ni, and Zn with respect to Italian, Chinese, and Dutch tolerance limits, probably due to the presence of these elements in ophiolitic rocks and sulphide-bearing deposits, used as raw material in building activity. Inductively coupled plasma mass spectrometry analyses of leachates, performed to assess the mobility of heavy metals, show significant concentrations of Cr, and to a lesser extent, Ni. Results suggest that homogenisation processes of the recycled materials should be implemented and preliminary screening of C&D waste should be performed to eliminate heavy metals-bearing components.
