“…The search for different approaches for the conservation of artworks and buildings, such as paintings, sculptures, decorating objects, furniture, bones and other objects that have lost their usefulness or mechanical features due to human usage or aging process, is referred to as artwork conservation and restoration [ 1 , 2 , 3 , 4 ]. Because of deterioration, certain natural materials need to be fixed or even replaced.…”

In this work, the preparation and characterization of films based on polysulfone (PSF) filled with zinc oxide, ZnO, nanoparticles (NPs) are conducted. The novelty of this research mainly relies on two points: (i) the use of a commercial airbrush to prepare or modify materials, and (ii) the design of new materials (nanocomposites) for the consolidation and restoration of historical bones. To accomplish these objectives, free-standing thin films and ancient bone coatings of PSF/ZnO nanocomposites with different particle contents (0%, 1%, 2%, 5% and 10%, % wt) are prepared using a commercial airbrush. Mechanical characterization is carried out to correlate properties between free-standing thin films and coatings, thus understanding the final performance of the coatings as consolidants for ancient bones. Thin films of PSF/ZnO show that the elastic modulus (E) increases with particle content. The mechanical behavior of the surfaces of the treated and untreated bones is studied locally using Martens hardness measurements. Maximum values of Martens hardness are obtained for the bone samples treated with polysulfone filled with 1% ZnO nanoparticles (HM = 850 N·mm−2) or 2% ZnO (HM = 625 N·mm−2) compared to those treated just with neat PSF (HM = 282 N·mm−2) or untreated bone (HM = 140 N·mm−2), indicating there is a correspondence between rigidity of free-standing films and hardness of the corresponding coatings. In terms of mechanical performance, it is demonstrated the existence of a balance between nanoparticle concentration and probability of nanoparticle aggregation, which allows better material design for ancient bones consolidation.

“…This causes misapplications in case of emergencies, and also may lead to future potential greater damages on the building. The lack of data regarding the engineering properties of these buildings causes long-term damages on the buildings due to inappropriate conservation methods and materials [41].

Today, the building materials form the historical buildings are being exposed to various deteriorations increasingly due to different causes. Many historical masonry constructions in the world are on the edge of extinction due to the increasing frequency and changing models of material deterioration. The materials as close as possible to the original materials in terms of their chemical compositions and physical properties are required in the reconstruction and maintenance of the buildings that have historical importance. In addition, the properties of the materials used in the historical buildings are generally not known with a sufficient accuracy. This causes misapplications in case of emergencies, and also may lead to future potential greater damages on the building. The lack of data regarding the engineering properties of these buildings causes long-term damages on the buildings due to inappropriate conservation methods and materials. Therefore, it is necessary to investigate the properties of certain materials for application in the renewal of the historical buildings. Within this context, in this study the construction materials of Mardin Castle, which is located in Mardin Province, Turkey and existing for centuries as the symbol of the city, are investigated and its properties are reached. Experimental research methods were used in the study. Primarily, the castle structure was examined on-site by field study and sampling was carried out from the areas determined. The samples were analysed via various spectroscopic and geophysical methods, and various findings were achieved. Relatively variable and high levels of salinization were determined in the findings regarding the average values in stone samples of Mardin Castle’s Fortification Walls. Results of the research document the conservation status regarding Mardin Castle and provide an experimental base and also a theoretical support for the conservation of historical buildings in Turkey; and present indicative suggestions to establish conservation schemes of the historical buildings.

“…Baseline chemical data on old lime mortars in Southeast Asian countries was reported from the Philippines, particularly from Christian church ruins in Manila (Cayme and Asor Jr 2016), Misamis Oriental (Cayme and Asor Jr 2017), Albay (i.e., Budiao and Cagsawa) (Laplana et al 2018;Mangay et al 2018), and a missionary chapel in Marikina (Cayme et al 2018). Furthermore, chemical investigations were also applied on lime mortars for future conservation works of different ancient Buddhist temples (wats) and a palace in Bangkok and Ayutthaya in Thailand (Mahasuwanchai et al 2020;Wonganan et al 2021), and the Fort Cornwallis in Penang, Malaysia (Harun et al 2002;Ismail et al 2003). Proper restoration of structures heavily damaged by earthquakes from the Dauis Church in Bohol, Philippines (Kalaw and Naguit Jr 2019), and Bagan temples in Myanmar (Thet Mon San et al 2018;Amadori et al 2019) have benefitted from the elemental data of lime mortars originally used in these structures.…”

Analytical Chemistry Methods of Estimating the Hydraulic Lime Characteristics of Mortars from a Spanish Colonial Period Fortification in the Philippines: Perspective of a Southeast Asian Country | Mga Pamamaraan ng Suriing Kapnayan sa Pagtantya ng Katangiang Haydroliko ng Apog sa Argamasa na Mula sa Isang Panahon ng Kastilang Kuta sa Pilipinas: Pananaw ng Isang Bansa sa Timog-Silangang Asya

This study has provided an analytical chemistry method to reveal the production technologies employed in lime mortar making from a Spanish Colonial Period fortification in Bacolod, Lanao del Norte, Philippines. Analytical techniques such as Energy Dispersive X-ray Fluorescence (EDXRF) and Thermogravimetric analysis (TGA) effectively provided general information on the chemical composition of the lime mortars and the hydraulic nature of the binder used. Mortar samples from different areas in the fort, were found to be made from a calcitic lime source possibly of marine shell origin. The hydraulic characteristic of both mortars is due to clay additives suggesting that local knowledge of this process is known during that period. The EDXRF and TGA techniques applied to the samples in this study will address the lack of systematic and detailed baseline chemical data on historical lime mortars in the Philippines and other Southeast Asian countries, which is vital for future conservation work in the ASEAN region. Ang pag-aaral na ito ay nagbigay ng isang maupanuring-kimika na pamamaraan upang maipakita ang mga teknolohiya ng paggawa sa argamasa na apog mula sa isang kuta na itinayo noong panahon ng mga Kastila sa Bacolod, Lanao del Norte, Pilipinas. Ang mga ginamit na instrument sa pananaliksik tulad ng Energy Dispersive X-ray Fluorescence (EDXRF) at Thermogravimetric analysis (TGA) ay mabisang nagbigay ng pangkalahatang impormasyon tungkol sa kemikal na komposisyon ng mga apog na argamasa at haydrolikong likas na ginamit. Ang mga argamasa na ginamit sa pagaaral na ito, na nagmula sa iba`t ibang mga parte ng kuta, ay natagpuan na ginawa mula sa isang calcitic na pinagmulan na maaring galing sa mga kabibe sa dagat. Ang haydrolikong katangian ng parehong argamasa ay dahil sa mga ihinalong luad na nagmumungkahi na ang lokal na kaalaman sa prosesong ito ay alam na ng mga gumawa nuong panahong iyon. Ang EDXRF at TGA na ginamit sa pagaaral na ito ay tutugon sa kakulangan ng sistematiko at detalyadong kemikal na datos sa mga makasaysayang apog na argamasa sa Pilipinas at iba pang mga bansa sa Timog-Silangang Asya, na mahalaga para sa gawaing kinabukasan ng konserbasyon sa rehiyon ng ASEAN.
