They are constructed as massive masonry walls with façade bricks attached to a core of massive red bricks. In the majority of these churches there is a presence of sodium sulphate causing salt damages. The source of the salts is known to be the red masonry bricks and the damage occurs both internally and externally on the walls. Damages occurred already after a couple of years after the churches were built and ever since they caused expensive renovations with little or no durability. As the sodium sulphate crystallizes inside the plaster the damages cause spalling of the surface. Since 2016 a method to prevent or delay salt damages has been studied and evaluated. By adding a layer of insulation on the internal wall the microclimate on and nearby the plaster surface can be changed and the damages caused by crystallization decrease. When adding an insulating layer made by hemp-lime plaster before adding the lime plaster the salts cause less visible damage to the internal plaster. Full-scale test surfaces have been made both in the laboratory and inside two churches. After two and three years respectively, there are no visible salts causing damages inside the churches, where salts previously came back directly after each renovation. In the wall in the laboratory at Lund University the bricks where contaminated with sodium sulphate and internally rendered with hemp -lime plaster with a lime plaster surface finish. Even though there are lots of salt-related damages externally there are thus far, more than two years after construction, no signs of any damage internally.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Balksten, K. and Strandberg-de Bruijn, P. } }

Between 1953 and 1955 the building underwent an important architectural and painting restoration project. Since 2017 the University of Applied Sciences and Arts of Southern Switzerland (SUPSI) is involved in the study and conservation of the wall paintings. Following preliminary research aimed to collect background information, a thorough condition assessment identified and mapped the different deterioration phenomena affecting the interior surfaces. The most challenging deterioration problem is related to the presence of soluble salts. The on-going diagnostic study includes the identification of the salts, their crystalline habits and the interior microclimate. This is necessary to plan an adequate intervention to stabilize the wall paintings. Salts efflorescence were analyzed with Polarized Light Microscopy and FT-IR ATR spectroscopy. Moisture distribution and hygroscopicity were assessed in various interior and exterior points through microcore sampling. The results showed that salt efflorescences are mainly composed of gypsum and epsomite and that moisture is present due to capillary rise and infiltrations. The presence of gypsum is due to materials used in previous interventions. The deterioration mechanism is on-going and during the first wall painting conservation campaign ( Fall of 2020)the decision was taken not to treat the areas actively affected by salts, but to monitor them over time in order to understand their behaviors and take an educated decision in the near future.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Caroselli, M. and Iazurlo, P. and Acquistapace, G. and Uccelli, M. and Guglielmetti, M. and Pidò, A. and Piqué, F. } }

To assess the situation and provide advice, both moisture and salt contents were analysed. The actual and hygroscopic moisture contents were determined gravimetrically, and the quantification of the ions was carried out by ion chromatography. The results show extreme concentrations of moisture and salts, with salt contents, excluding gypsum, up to 17 wt.%, containing, besides sodium carbonate, mainly sodium chloride and sodium sulfate and in lower quantities also potassium chloride and potassium nitrate. The results show extreme concentrations of moisture and salts. The values of the ion mixtures were used to model the behaviour of the salts in changing climatic conditions with ECOS/RUNSALT. Furthermore, the theoretically determined crystalli sation behaviour of several salt solutions was further investigated within a micro-climate chamber at 95 %RH and Raman spectroscopy. At this RH gypsum and gorgeyite formed in the salt solution derived from the plaster.

The brick samples were first freed from salt and then exposed to controlled sodium sulfate contamination. The sacrificial rendering mortar was applied to the salt-contaminated bricks. Half of the samples was left as-is, while the other half was placed in 1 cm water to mimic rising damp conditions. This procedure was repeated several times. After each application, the salt amount at different depths was measured in the bricks. The effect of biochar on the developed mortars and the desalination efficiency of the mortars were assessed, using Dino Lite digital microscopy, SEM-EDS, XRF, ion chromatography, XRD, and TGA-DTA.

Techniques based on electro-osmosis have been proposed as conservation methods to dehumidify masonry subjected to capillary suction. Although electroosmotic techniques have been applied for decades, the effect is still debated.This paper reports an experimental investigation on electro-osmosis in single bricks in a laboratory setup originally designed for electro -desalination. Two types of bricks were used. The samples had different lengths and different initial water content. A poultice composition was designed with neglectable electroosmotic effect and effective buffering of the acid produced from the electrode process at the anode. Four poultices with different concentrations of CaCO3 and kaolinite were examined, and the poultice consisting of calcium carbonate:kaolinite:water with the ratio of 40:10:50 (wt  %) fulfilled the requirement. It was seen that more the kaolinite in the mixture, more the electro-osmosis. A constant voltage of 75V was applied to the electrodes in each end of the setup. The zeta potential of the bricks was comparable to the zeta potential in kaolinite, and thus electro-osmosis in the bricks was expected. However, the water content reached saturation all through the brick specimens in every experiment, and there was no difference in water content in the two poultices. Thus, the capillary forces causing water suction into the bricks from the poultices were the strongest and overshadowed the possible electroosmotic effect. Therefore, this work shows that capillary forces need to be taken into account when designing setups for evaluation of electro-osmosis in materials with strong capillarity. The same is valid for in real applications, in case a continuous source of water is present.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Eslami, N. and Feijoo, J. and Paz -Garcia, J. and Franzoni, E. and Ottosen, L.

To fight saltinduced deterioration of stone, different treatments were recently proposed, aimed at modifying the crystallization of salts during either the nucleation or growth of the crystals. In particular, strategies based on crystallization inhibitors and promoters were studied in the literature. In this paper, a new two-step treatment was applied to Globigerina limestone samples. The treatment consists in the application of an aqueous solution based on diammonium hydrogen phosphate, followed by the application of a chitosan solution. The first one produces aninorganic layer of calcium phosphate phases (mainly hydroxyapatite) and is aimed not only at consolidating the stone and preventing calcite dissolution, but also at providing a rough anchoring substrate for chitosan. The second layer is formed by chitosan, a biopolymer that was shown to have an inhibiting action on the crystallization of sodium sulphate. The two solutions were applied to the limestone samples both alone and combined, adopting different concentrations.The effects of the treatments were investigated in terms of phase formation, pore size distribution modification and change in the dynamic elastic modulus. Then, treated and untreated limestone samples were subjected to an accelerated crystallization procedure in laboratory, to evaluate the benefits deriving from the treatments. }, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Franzoni, E. and Sassoni, E. and Marrone, C.} }

Considering that salts tend to follow the path of least resistance when crystallizing, the pore space needs to be filled for damage to occur. Only when such a condition is achieved, the growing crystals can exert enough pressure against the pore wall to initiate the damage. However, calculating the pore filling is a tedious task and often overlooked. This paper discusses the results of two methodological approaches to estimate the pore filling in Maastricht stone samples subjected to sodium chloride and sodium sulfate contamination. The investigation is part of an ongoing technical committee developing a laboratory test to assess the durability of porous materials to salt crystallization (RILEM Technical Committee 271-ASC). The first method exploits an image analysis approach using scanning electron microscopyon polished crosssections. The second method follows a theoretical approach based on the salt content data determined by ion chromatography, the molar mass and volume of Na2SO4(thenardite) and NaCl, the dry bulk density and o pen porosity of the Maastricht limestone. The deviations observed in the results from the two methods are discussed with respect to the potential methodological issues. Some possible strategies to mitigate such discrepancies are proposed. }, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Gulotta, D. and Godts, S. and De Kock, T. and Steiger, M.} }

The gypsum content is always very low at the surface and progressively increases (always around 1%) up to the depth of the zone where the crack is present, and then decreases along depth. No other salt was detected. This study also proved that preexistent cracking is not necessary for gypsum to crystallize.

The salt weathering is attributed to the stress developed from crystallisation of these salts in pores of the building materials, with supersaturation as the driving force. In the last years, researchers have successfully mitigated the damage associated with the crystallisation of NaCl by the use of alkali -ferrocyanides (crystallisation inhibitors) in porous building materials. The observed mitigation of the damage has been attributed to lowering of the crystallisation pressure, possibly related to changes in the crystal habit and preferential crystallisation of the salt in the form of efflorescence instead of crypto-florescence. However, the effect of the inhibitor on the development of the so-called crystallisation pressure has not been studied in detail yet. In fact, direct measurement of this pressure is challenging and, until now, only a few experiments have been successful. In this research, an experimental set-up has been developed to directly measure the crystallisation forces of NaCl and the effect of fer- rocyanide on these, while visualizing the crystallization process under a microscope. Some preliminary tests using this set-up have been carried out: these consisted in monitoring force evolution from a drop of solution with and without the inhibitor confined between two glass plates.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Kamat, A. and Lubelli, B. and Schlangen, E.} }

The results, which are entirely in line with complementary μ-XRF measurements, vividly show changes in the microstructure of the salt-contaminated samples.

Restoration mortars containing Portland cement and additives were not included. The 15th century brick wall is approximately 3 m high and has a 1.5 m backfill of soil. The water content of the wall was monitored with a dielectric probe at three levels above the ground. The average moisture content changed during the test period in accordance with the rainfall. There was an increase in wet seasons and decrease in dry seasons. The drying rate was rapid and almost independent of the type of render. The main source of moisture was the soil at the back side rather than driving rain at the front side. The decay related mainly to the thickness and the composition of the plaster. Two or three layers of hydraulic lime mortars were the most resistant to weathering, whereas a single layer of lime mortar was the least durable. It is difficult to predict the lifetime of the renders based on the performance in the first five years.

The degradation can lead to fractures and/or loss of cohesion among the individual particles forming the material components. It can also damage the painting layers: flaking of the surface layers, powdering etc. To protect weakened porous materials, filmforming substances, resins and polymeric materials are often used to consolidate weakened porous objects and structures. Although progress has been made in improving consolidation treatments for silicate stones, the treatments are much less effective when used on carbonate stones (such as marble or limestone) because of the chemical incompatibility between the grains and the common treatments. Here, we present a novel two-step treatment for consolidating weakened artworks made of porous limestone. Coupling agents are synthetized as a pre-treatment step to prepare the porous net work prior to the application of the consolidant. The latter can then be applied successfully without inducing crack formation during drying. The efficiency of the two-step treatment was studied at the microscale and linked to the macroscopic mechanical properties, such as the Young’s modulus and stress at break of the materials after treatment. Our results have advantages over other types of the treatments based on lime nanoparticles: the two-step treatment proposed here is easy to implement while being eco-friendly. In addition,it respects several other important criteria, such as the ability to restore the mechanical properties of damaged stones without changing their physical appearance and other properties, such as porosity or permeability. }, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Le Dizès, R. and Jaïs, D. and Shahidzadeh, N.} }

This paper focuses on the salt accumulation phase; this phase should promote salt crystallisation close to the evaporative surface of the substrates (common situation onsite) without leading to salt efflorescence or damage. Damage should take place in the propagation phase, which is not add ressed in this paper. This work compares the effectiveness of three contamination procedures for salt accumulation: P1) salt contamination by capillary absorption of salt solution, followed by drying; P2) continuous capillary absorption of salt solution; P3) placement of salt crystals on the surface of the materials followed by the conditioning of the specimens at high relative humidity until complete dissolution of the salts. The results of P1 and P2 procedures presented in this paper are detailed in a sep arate publication, while this paper focuses on P3 procedure and compares the results. The effectiveness of each procedure has been evaluated by assessing the salt distribution in the specimen using ion chromatography and scanning electron microscopy. The r esults show that P3 is technically the least complicated to set up and does not entail the risk of development of salt efflorescence or damage. However, it can lead to salt migration within the specimens to a greater depth, hence future research is proposed to counteract this effect.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Nunes, C. and Godts, S. and Aguilar Sanchez, A.M. and Slížková, Z. and Lubelli, B.} }

For the further development of these methods, increased understanding of the influence from side effects on the transport of the target ions is necessary. Electromigration has most often been investigated under application of a constant current. In this work, a constant voltage is applied, and it reports a direct comparison of electromigration of K+ and NO3- through substrates with different porosities. Prisms, one brick and four natural stones, were prepared and contaminated with NaCl in exactly the same way. Electromigration experiments were made under the same applied constant voltage. During the first hours, the current was very different between the experiments (from 2.3 to 72 mA), showing major difference in the electrical conductivity of the substrates - the higher the porosity, the higher the conductivity (and current). The current developed differently between the experiments. By the end of the 3 days experiments, the current was between 3.4 and 9.2 mA and independent of the substrate porosity. During the experiments, the electrode processes and the connected side effects influenced the electromigration of K+ and NO3- to different extents in the different substrates, and the most in the substrates with high porosity. The experiments underline that the electromigration of target ions depends strongly on the substrate when applying a constant voltage, because the substrate conductivity determines the current and thus the side effects. Applying a constant current instead, as in most of the previous works, enables better managing of the side effects.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Ottosen, L.

These tiles were extensively used in buildings in the Netherlands, but they are also found as far away as Brazil. Today tiles are considered important cultural heritage with a clear historical value, but often also an aesthetic or even an artistic value. They may be valued as individual tiles, but it is important to also consider their value within an ensemble. Tin-glazed tiles that are still in situ can be badly affected by crystallizing salts. Unfortunately, it is the most defining part of the tile, the glaze-layer, that is most vulnerable. The conservation of tin-glazed tiles affected by soluble salts often requires invasive treatments including removing the tiles fr om their location and desalinating them in water. Such treatment is not without risk for the tiles. In other situations, tiles might have to be replaced with replicas or similar contemporary tiles. In order to be able to justify any such treatment it is important for the conservator to acquire a better understanding of the causes of the salt crystallization. This requires research, performed by a researcher specialized in this field, and which should include investigations into the moisture sources and the amount and type of salt ions that are present. This information is often necessary in order to determine a conservation strategy that best preserves the value of the tile with as minimal intervention as required. For the preservation of tin-glazed tiles it is important that the value of research is better understood by both conservators and other stakeholders. }, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Overhoff, M.

With two desalination projects in Amsterdam in the last 2 decades, we’ve worked alongside the researchers of TNO and TU Delft to find solutions to create the optimal conditions for large scale desalination in situ.In project ‘De Waag’, the mail goal was to conserve the Masterpieces of masonry from the 17th century, which were damaged by mostly NaCl2. For an in-situ treatment we have looked at methods suitable to use at large scale. This resulted in a mechanical application of the poultice by spraying. While the treatment to reduce the saturation of salt was successful, a post -treatment was needed in order to clean the masterpieces of the debris left by the clay (kaolin) in the poultice. With knowledge of the Waag, the tower of the Zuiderkerk (1614), offered a new challenge. In this case sodium sulphate was the dominant salt responsible for degradation of the masonry. Reducing sodium sulphate has more risks, and those risks can only be controlled while applying a poultice in warmer condition. The main goal was to find a solution to partly heathen the wall on those parts of the tower where salt load was too high. Trying several electrical heating systems, we’ve found the most ideal option. Both projects resulted in some practical and effective options, but also lessons learned by all the trails conducted. Main conclusion is that large scale in-situ desalination is possible, and methods to make it effective can be useful for other projects, but only after extensive research and monitoring.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Pater, R.} }

Some of the contaminated samples have been artificially weathered. Salt contamination and weathering methodologies are based on those proposed by the RILEM Technical Committee TC 271-ASC (see Lubelli et al. paper in this conference, [1], [2]).

Their finely porous and decorated surface is exposed to the environment and their support may be connected to ground or infiltration water, both making it susceptible to salts. While hygroscopic salts usually enter the pore network of objects via ground or infiltration water, the formation of gypsum, which is often present as a superficial crust, is the result of acidic deposition of SO2 from the environment. Even though air pollution has decreased in recent decades, many objects are still affected by these crusts, which represent a serious risk, especially for sensitive wall paintings. The“barium method” developed in the 1960s represented a huge progress in the conservation of wall paintings by successfully combining the removal of gypsum and the consolidation of the porous structure. However, pertinent literature describes the issue of hygroscopic, nitrate -containing pore solutions already present in the object that allow the formation of more soluble barium nitrate, if these nitrates were not effectively removed before the application of the method. Despite this warning, the actual damage potential of Ba(NO3)2 has not yet been investigated. This study focusses on damage aspects of barium nitrate and discusses results of damage tests and considerations of the damage related behavior of Ba(NO 3)2, also in hygroscopic salt mixtures.

Two different approaches were tested on marble: part of the specimens was treated by a single solution containing both NaCl and DAP (“NaCl+DAP” samples) and part of the specimens was subjected to a two-step treatment, consisting in preliminary contamination by NaCl and subsequent consolidation by DAP (“NaCl then DAP” samples). For each approach, different NaCl and DAP concentrations were tested. The new phases, formed after treatment, were characterized by FT-IR and SEM and their consolidating effect was assessed by ultrasonic measurements, in terms of increase in dynamic elastic modulus (Ed). To investigate the influence of the NaCl contamination on the durability of the consolidating treatments, consolidated specimens were repeatedly immersed in water, the solubilized ions were analyzed by ion chromatography and the possible decrease in consolidating efficacy was assessed by Ed. The results of the study point out that, following either approach, new calcium phosphate (CaP) phases were formed, identified by FT-IR as hydroxyapatite and/or octacalcium phosphate. These new phases led to significant increases in Ed, which experienced some reduction when the consolidated specimens were immersed in water. Nonetheless, the residual Ed was sensibly higher than in the untreated condition, indicating that a significant mechanical benefit was maintained. The “NaCl then DAP” samples, which resemble the actual situation in the field, seem to provide more reliable results than those obtained following the alternative approach. In fact, the combined treatment (“NaCl+DAP”) led to lower increases in Ed and less pronounced formation of new CaP, possibly because the presence of sodium and chloride ions in the DAP solution significantly altered the mechanisms of CaP formation.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Ugolotti, G. and Masi, G. and Sassoni, E.} }

The thickness and the shape of the damaged layers of the stone were variable. Laboratory research has shown a high concentration of soluble salts (chlorides, sulphates and nitrates, dominantly halite and gypsum), which caused accelerated decay of the limestone; therefore, the conservation-restoration process was focused on different desalination methods. Water baths were chosen for the desalination method, followed by barium hydroxide treatment. Before and after the desalination treatment, stone was consolidated by nano-lime. After the treatment, the stone relief was stabilized and ready for return to stabile museum environment.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Ugrina, H. and Marinković, V. and Mudronja, D.} }

The salt observed on the chimney was determined to be sodium sulfate(Na2SO4). The exhaust gas of the boiler was the major source of water and sodium sulfate. The water vapour in the hot exhaust gas with salts would condense on the cold surface inside the chimney flue, resulting in salt solution penetration into the brick; subsequently, water evaporation at the outside surface would lead to salt crystallisation. Our field observation showed that salt crystallisation was concentrated at 1 m above the floor but did not occur above 2 m, at the level where an exhaust pipe of the boiler gas was connected to the brick chimney. According to the surface temperature measurement results, the temperature increase at non-weathered areas was larger than that at weathered areas. The CFD analysis showed that warmer air moved upwards above the exhaust duct, whereas colder air remained stagnant below the exhaust duct. This result suggested that both the airflow and the corresponding temperature distribution in the brick chimney flue influenced the spatial distribution pattern of salt weathering.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, fulltext = {File:Tomoko-etal 2021 1.pdf}, author = {Uno, T. and Abuku, M. and Iba, C.} }

Both lime mortar and a specially designed salt-extraction mortar were tested as a sacrificial plaster. The main problem was that the salt redistributed within the vault because of the water supplied by the mortar.

For the purposes of this paper calcium nitrate, a deliquescent salt commonly found in wall paintings, was selected to clarify the role played by very hygroscopic salts in wall painting deterioration. The most suitable methods for analysis of calcium nitrate tetrahydrate have been identified, the environmental conditions under which salt activity may occur checked and some physicochemical parameters suggested for controlling the environment in order to avert such activity. The kinetics of water sorption have been studied to identify the various factors which might affect the rate of deliquescence. The variables included the mass of the salt, the presence of other salts, and the kind of support on which the salt is deposited. Thermogravimetry and differential thermal analysis (TG-DTA) were found to be the most reliable and practical techniques to identify the salt. Calcium nitrate tetrahydrate was found to deliquesce easily and recrystallize under environmental conditions typically prevailing for wall paintings. of the variables studied, the support had significant effect on the water sorption kinetics and, most significantly for wall paintings, it was found the deliquescence would occur most rapidly in plaster. -- CAL}, author = {Piqué, F. and Dei, L. and Ferroni, E.} }

It starts from the consideration that it is necessary to accumulate a certain amount of salt to activate the damage. Thus salt damage can be seen as a process developing in two phases: accumulation and propagation. Based on this approach, a new salt crystallization test procedure has been defined, consisting of two phases: a first phase, in which salts are introduced in the material and accumulate close to the evaporation surface, followed by a second phase, in which damage propagates because of repeated dissolution and crystallization cycles induced by re-wetting with liquid water and by relative humidity (RH) changes. In this paper the procedure is described and the reasons for the choices made are elucidated. The procedure has been tested on two types of limestone and, at the moment of writing, is being validated in a round robin test carried out on 9 different substrates and involving 11 laboratories. Based on the results of the round robin test, the procedure will be fine-tuned.}, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Lubelli, B. and RILEM TC 271-ASC members} }

A derivation of an equation for the crystallization pressure based on the chemical potentials of the loaded and the unloaded faces of a growing crystal is provided. The equation obtained is compared to other equations available in the literature and the different approaches are discussed in detail. The treatment also includes the non-ideal behavior of the liquid phase using the ion interaction approach (Pitzer equations) which is well-established in solution thermodynamics. Incorporating the ion interaction equations in the crystallization pressure equation yields a quite simple expression that appears to be more convenient than previous treatments. The equation is applied to calculate crystallization pressures for supersaturated solutions of aqueous NaCl, NaNO3, Na2SO4, and MgSO4 including the various hydrated forms of these salts. Depending on the nature of the salt, neglecting the non-ideal behavior may cause considerable error in crystallization pressure calculations. Finally, it is emphasized that the basic assumption of non-uniform pressure is fundamental to understand the dynamics of crystallization pressure evolving in porous materials.} }
