Conference Object Citation - WoS: 3Citation - Scopus: 4Properties of Roman Lime Mortars in Ancient Lycia Region(American Institute of Physics, 2018) Taşcı, Burcu; Böke, HasanIn this study, the characteristics of mortars used in some ancient Roman buildings located Xanthos (Antalya), Patara (Antalya) and Tlos (Mugla) in Southern Turkey were determined in order to define the properties of the new mortars to be used in the conservation works of the buildings. For this purpose, their basic physical properties, raw material compositions, mineralogical and microstructural properties were determined by X-Ray Diffraction, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy coupled with X-Ray Energy Dispersive Spectroscopy. Analysis results indicated that the binder of the mortars composed of lime and fine aggregates have compact and uniform structure. The mortars are of low density and high porosity were produced from high calcium lime containing magnesium and natural aggregates. The lime and aggregate ratios were between 3/4 - 5/2 by weight and the aggregates with particle sizes greater than 1mm. composed the largest fraction of the aggregates. Lime composed of small size of micritic crystals due to use of aged lime puny. Aggregates were natural and mainly composed of quartz, albite, diopside and amorphous silica that may derived from the use of volcanic ash as pozzolans.Article Citation - WoS: 16Citation - Scopus: 19An Evaluation of Decision-Making Process on Maintenance of Built Cultural Heritage: the Case of Visby, Sweden(Elsevier Ltd., 2019) Eken, Esra; Taşcı, Burcu; Gustafsson, ChristerPreventive conservation is a significant approach for the conservation of built cultural heritage. This approach aims to prevent major deteriorations through monitoring and a planned maintenance programme. Although Visby, as one of the most important world heritage sites of Sweden, has many governmental organizations for conservation, none has a particular focus on maintenance. This paper examines the perspective of the habitants about the maintenance of their dwellings in the World Heritage Site of Visby. In this context, a survey is carried out to determine the main tendency of the habitants regarding the maintenance of historic buildings inside the city walls. Thus, the survey requires not only quantitative methods based on statistical data, but also qualitative methods based on interpretative data. The questionnaire conducted with the owners and tenants is the primary data collection tool. Both the owners and the tenants agree with the necessity of a non-governmental organisation in Visby to provide advice on maintenance. Maintenance and regular monitoring prevent costlier and large-scale repairs and are essential to retaining the cultural significance of Visby. This study can be helpful for adopting the community's opinion to the regular maintenance programme and promoting cooperation between non-profit organizations and governmental organizations in cultural heritage.
