“…For all the proposed materials, was also observed a decrease in the capillary water adsorption coefficient. Similar approaches were published by Moropoulou et al [116] (using several pozzolanic additives), Andrejkovičová et al [117] (using palygorskite and metakaolin), Ventolà et al [118] (using commercial phase changing materials), Rosato et al [119] (using commercial cellulose nano-fibrils), Gour et al [120] (using natural polymers) or Pavlík et al [121] (using crushed lava granulates). However, regarding the reconstruction/consolidation mortars, the best approach, in our opinion, is the one presented by Stefanidou et al [122], respectively designing the mortars according to the nature of the natural stone (in the cases presented by the authors marl limestone, nummulitic limestone, marble, biogenic calcitic sandstones), and as, often as possible, reclaiming local materials.…”

Vernacular buildings are usually constructed using materials at hand, including wood, natural stone and bricks (either clay or mud bricks). All those materials are exposed to a series of environmental factors, affecting their structure and integrity. The literature review was conducted using different databases (Scopus, Web of Science, ScienceDirect, SpringerLink) using as keywords the historical material, "heritage" and the terms regarding the desired effect, within the envisaged time period (2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019). The assessment of the results was performed by manual inspection (reading the entire article) and the selection of the works to be inserted in the current review was made by evaluating the contribution to the field. This review summarizes different aspects related to the restoration and conservation of wooden and masonry elements of traditional buildings, including materials used for biocidal interventions, protection against abiotic factors, cleaning and consolidation agents. Finally, a critical discussion regarding the current limitations and future perspectives concludes the review work, envisaging the role of researchers specialized in materials science in the context of cultural heritage conservation.

“…When looking at the other similar studies, summarized in Table 4, it appears that only five of them use the same PCM as in the present study. Besides, as stated before, some of them only deal with DSC [40,45,82] and the properties of a real macroscopic sample are addressed solely by [35], although only the thermal conductivity is involved in the latter paper. More importantly, when dealing with the thermal conductivity, very often, only an overall or effective value is furnished and no distinction is done between the concrete with PCM in solid or in liquid state, contrary to what is currently done here.…”

Efficient Characterization of Macroscopic Composite Cement Mortars with Various Contents of Phase Change Material

The determination of both the thermal and thermodynamical properties of a composite material containing phase change material is done thanks to an inverse method, which combines experimental measurements and numerical computations. Given first an in-house experiment, which allows us to test samples at a macroscopic scale (i.e., close to the real conditions) and to set various types of thermal stresses, and secondly the simulation of the corresponding thermal behavior, relying on an accurate thermodynamical modeling and taking into account the real operating parameters (e.g., thermal contact resistances and non-symmetric heat fluxes on each side), it is possible to characterize the solid and liquid thermal conductivities and heat capacities, as well as the temperature range associated with a non-isothermal phase transition and the associated latent heat. The specificity of the present approach is to allow, in a single step, a characterization of all the involved thermo-physical parameters that are usually required in simulation tools (e.g., EnergyPlus…). Moreover, the hitherto studies dealing with repeatability and uncertainties of the enthalpy characterization are generally very scant and not encountered very often or only with qualitative assessments. This is a clear caveat, especially when considering any system design. Therefore, for the first time ever, the present paper pays a special attention to the repeatability of the identification method and studies the scedasticity of the results, that is to say the deviations of the determined enthalpy curves, not only from a qualitative point of view but also by proposing quantitative arguments. Finally, the results are very promising since the agreement between all trials is excellent, the maximum error for all parameters being lower than 4%. This is far below the current quality thresholds admitted when characterizing the enthalpy of a phase change material.

“…Despite its small volume, the mortar is an integral part of the structure, which is a very effective and crucial material for masonry structures. Lime-based mortar was firstly used in the Middle East and Anatolia almost 14,000 years ago (Ventola et al 2013). Recently, lime-based mortar has been commonly used in both repairs and restoration applications of historical and ancient structures (Ventola et al 2011;Lanas and Alvarez, 2003).…”

Lime-based mortars have been used as bonding materials between stones or bricks since ancient times. It is an integral part of many structures and generally is used to fill the gaps between construction blocks (mortar joint) and strengthen the structures. Nowadays, different organic and inorganic substances are added to mortars in order to improve their physical and mechanical properties. This study deals with the combined effects of chopped carbon and glass fibres on mechanical properties of hydraulic lime-based mortar. Accordingly, lime-based mortar is prepared and chopped carbon (CCF) and glass (CGF) fibres are used as reinforcing materials in the lime-based mortar (1% by plain mortar weight). Five different combinations are investigated: Mixture-1 (100% CCF + 0% CGF), Mixture-2 (75% CCF + 25% CGF), Mixture-3 (50% CCF + 50% CGF), Mixture-4 (25% CCF + 75% CGF), Mixture-5 (0% CCF + 100% CGF). After reinforcing process, mechanical characterization tests are conducted on the mixtures at the end of 28 days curing. In the second stage, scanning electron microscope (SEM) observations and high definition visual inspection are carried out in order to investigate the interface mechanism between fibres and mortar. In the third stage, one-way analysis of variance (ANOVA) is performed to see whether differences between mechanical properties are statistically significant.
