Article Citation - WoS: 1Citation - Scopus: 1Properties of Roman Structural Mortars in the Province of Asia (turkey)(Elsevier Sci Ltd, 2025) Tasci, Burcu; Boke, HasanIn this study, the properties of Roman structural mortars composed of lime and natural aggregates from twentythree archaeological sites in Western Anatolia were determined in order to understand whether there was a common production technology of lime mortars in the Roman Empire by making a comparison between Europe and Western Anatolia. Their basic physical and mechanical properties, raw material compositions, microstructural and hydraulic properties, mineralogical and chemical compositions of their lime binder and fine aggregates were identified by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy coupled with energy dispersive spectroscopy, thermal gravimetric analysis analyses, bulk density, total porosity and compressive strength of mortars. The results indicated that these mortars mortars were produced by combining fat or lean lime with coarse aggregates (quartz, tuff) and predominantly fine pozzolanic rhyolitic and dacitic tuff aggregates. The lime/aggregate ratios of the mortars generally exhibited a range of values between 1:4 and 1.5:1 by weight, which closely paralleled the lime/aggregate ratios in other Roman mortars published in literature. The presence of lime lumps within the mortar matrices, exhibiting a spongy texture, may suggest the use of the hot lime mixing method in the preparation of the mortars. The mortars are hydraulic, possessing compressive strengths comparable to those observed in natural hydraulic lime mortars (NHL2, NHL3.5 and NHL5 types). The results indicate that the production of structural mortars in the province of Asia was similar to that in other regions of the Roman Empire, although the raw materials are similar, small differences in raw material composition could be due to the use of local raw material sources. This may be evidence of a common lime mortar technology that deliberately used pozzolanic aggregates with almost pure lime throughout the Roman Empire.Article Art and Construction Related Qualities of 14th‒15th Century Monuments in a Rural Landscape on the Western Coast of Türkiye(KeAi Communications Co., 2024) Hamamcıoğlu Turan, Mine; Aktaş, Engin; Toköz, Özge DenizThis study aims to contribute to the understanding of the evolution of art and construction in the early settlements established by Turkish communities on the far west Asian coast by focusing on two developed examples in Urla Peninsula. Conventional surveying and evaluation techniques of architectural restoration and civil engineering were utilized. Key findings include the understanding of the hierarchy of rural settlements in the studied landscape: old Çesme the most developed village of peninsula in the 16th century. It was positioned along a valley in distance to coast, but in control of harbor that played significant role in commerce between Europe and Asia. Its mosque and tomb, dated to late 14th – early 15th centuries, used to crown it. Cylindrical minaret tower of mosque, domed tomb tower on a cubical base and squinch in the transition zone of mosque are evidences for Central Asian roots. Usage of local lime stone, re-usage of andesite blocks, framing of the stone blocks with bricks, and pendentive in tomb refer to Roman-Byzantine constructions. The study presents the development of Turkish art and construction on the far west Asian coast in the 14th‒15th centuries. Findings will be a guide for related conservation management in similar contexts. © 2024 The Author(s)Article Citation - WoS: 19Citation - Scopus: 20Execution Technique and Pigment Characteristics of Byzantine Wall Paintings of Anaia Church in Western Anatolia(Elsevier Ltd., 2018) Demir, Serap; Şerifaki, Kerem; Böke, HasanIn this study, material characteristics of wall paintings executed in 11th Century Byzantine Church located in archaeological site of Anaia (Turkey) were investigated to provide historical information of the painting techniques. For this purpose, physical, chemical and mineralogical compositions of the paintings were determined by X-Ray Diffraction, Fourier Transform Infrared spectroscopy, Scanning Electron Microscopy coupled with Energy Dispersive spectroscopy and Thermo-Gravimetric Analysis. Analysis results indicated that the paintings were executed using lime-secco technique. In this technique, pigments were mixed with lime and applied on a smooth plaster layer. Pigments used were mainly iron oxides for red, yellow and purple paintings, aluminosilicates such as celadonite for green paintings and lazurite for dark blue paintings.
