“…Their study for restoration purposes requires a multidisciplinary approach; various types of analysis can be made to provide useful data for a full characterization of the binder and aggregate fractions and for the identification of their raw materials including special additives. Optical microscope observations and calcimetry, XRF, XRPD, TG/DSC, SEM/EDS analyses are the methodologies usually performed in the research activities on mortars from historical buildings [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], although there are works in which statistical analysis [23], Fourier transform infrared spectroscopy [24,25], mercury porosimeter [26,27], gas adsorption analysis [26], digital image processing [28], atomic absorption spectroscopy [29], inductively coupled plasma-mass spectrometry [29], physical and mechanical testing [30][31][32][33] are also used.…”

“…In fact, sample OP4 showed a band the position of which may be largely due to the presence of recarbonated lime, whereas sample OP9 showed a large spread band with three shoulders, which confirmed the presence of carbonate with different crystalline phases. Moreover, the high amount of carbonate in sample OP9 (i.e., ~41%) could be due to the presence of the carbonate aggregate, which alters the CO 2 /SBW ratio (Drdacky et al ). A further difference can be observed in the 200–600 °C region.…”

Roman plasters sampled from different houses at the archaeological site of Herculaneum, Italy, (2010–12) were studied by means of petrography, thermal analysis and X‐ray fluorescence. Herculaneum plasters are composed by preparatory layers (arriccio) with a thickness of several centimetres and are based on a calcitic binder and volcanic scoriae as aggregates, covered by a thin final layer characterized by a low granulometry. Most of the sampled plasters can be placed into two groups based on the aggregate composition and classified as marmorino or intonachino. However, a similar aggregate composition did not induce superimposable thermal behaviour, thus suggesting that the samples underwent different ageing/weathering processes, with a consequent change of the ratio among the components.

“…Although there are an appreciable number of studies on concrete and mortar, definite conclusions on the size and shape effects for natural building stones are very limited (Kourkoulis & GanniariPapageorgiou 2010). Correction functions, in general, depend on the length of the base edge, height and quality of the specimens (Drdácký et al 2013). Considering the dimensions of the specimens, a coefficient of 0.40 for the lime mortar specimen (Drdácký et al 2008;Drdácký 2011) and a coefficient of 0.65 for the stone specimen (Del Viso et al 2008;CEN 2011c) were used.…”

Laboratory testing of non-standard original historic building materials and related implications for conservation

For an assessment or an analysis of a historic building, determination of the material properties is always crucial. However, this is usually a challenging issue because material extraction from a historic building for standard laboratory testing is usually not allowed or the amount of material available for testing is very limited. Lack of comprehensive standards for testing irregularly shaped and non-standard-size specimens, taken from historic buildings, unfortunately compounds the uncertainty. This paper offers a discussion of such issues by using the case study of Odda's Chapel in Gloucestershire, UK, and describing the systematic examination of a total of six lime mortar and Blue Lias stone samples extracted from this Grade I listed building. The programme of testing and the results obtained are compared with the latest European standards relating to sampling and testing of material of cultural properties. Internal microstructure, hygroscopic sorption and water absorption characteristics, and the density and mechanical properties of the materials are documented and alternative testing techniques are compared. Identification of some of the above-mentioned material properties shows that the agreement between results obtained from the various test methods is considered satisfactory, depending on the testing approach and material heterogeneity.
