    Brick-lime mortars and plasters have been widely used as water-proof materials in aqueducts, bridges and cisterns since early Hellenistic time. In this study, the characteristics of brick-lime plasters used in some Ottoman bath buildings were investigated in order to understand their relevance as plasters in hot and humid environmental conditions of the baths. For this purpose, basic physical properties, raw material compositions, mineralogical, microstructural and hydraulic properties of brick-lime plasters of some historic bath buildings in İzmir (Turkey) were determined by XRD, SEM-EDX, AFM and chemical analyses. The results indicated that their survival without loosing their strength and adhesion in hot and humid conditions of the baths was explained by their hydraulic characters due to the consciously use of porous and pozzolanic crushed bricks as aggregate in the manufacturing of plasters.

    Characteristics of Lime Produced From Limestone Containing Diatoms
    (Elsevier Ltd., 2008) Böke, Hasan; Çizer, Özlem; Şerifaki, Kerem; Uğurlu Sağın, Elif; Şerifaki, Kerem; İpekoğlu, Başak; Uğurlu Sağın, Elif; Böke, Hasan; 02.01. Department of Conservation and Restoration of Cultural Heritage; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    In this study lime binder used in stone and brick masonry mortars of some historic Ottoman baths was examined to understand whether the binders were hydraulic or not. For this purpose the mineralogical and elemental compositions and the microstructure of lime binder were determined by XRD, SEM-EDS and TGA analyses. The results indicate that the lime used in the brick dome mortars of Ottoman baths was hydraulic. Taking into account the kiln and fuel conditions of the 15th century, the possibility of obtaining hydraulic lime at relatively low temperature was examined. For this purpose limestone containing diatoms was heated at a relatively low temperature (850 °C), then slaked and carbonated. After heating and slaking, calcium silicate giving hydraulicity to the lime was indicated by XRD and SEM-EDS analyses. These results show that the production of hydraulic lime at a relatively low calcination temperature (850 °C) was possible with 15th century kilns.
