    Microstructural Characteristics of Mortars Prepared by Hot Lime Mix
    (Union of Croatian Civil Engineers and Technicians, 2020) Şerifaki, Kerem; Uğurlu Sağın, Elif; Böke, Hasan
    The effect of lime characteristics and hot lime mix method on hydraulic, microstructural and mechanical properties of mortars is determined by producing mortars from quicklimes of two different marbles and two limestones. Results of SEM-EDS, XRD and TGA analyses reveal that the porous microstructure of mortars and spongy texture of calcite crystals are the indicators of the hot lime mix method. This study shows that characteristics of limestones used for the production of limes, as well as the preparation method, directly affect hydraulic, mechanical and microstructural properties of mortars.

    Anadolu’da Roma Dönemi Yapı Tuğlalarının Özellikleri
    (Gazi Üniversitesi, 2017) Uğurlu Sağın, Elif
    In this study, chemical and mineralogical compositions, physical, microstructural and pozzolanic properties of Roman Period building bricks taken from Kizil Avlu (Serapeum) in Pergamon and from several different buildings from ancient sites of Aigai and Nysa were determined by using XRF, XRD, FTIR, SEM-EDS and chemical analyses. Chemical compositions of bricks were evaluted by statistical analyses in order to identify whether or not these bricks were manufactured by using same natural raw material sources. Analyses results indicated that Roman period building bricks were manufactured by using calcium rich clay sources and fired at low temperatures (<900°C). Brick samples were mainly composed of quartz, albite, anorthite, muscovite and hematite. Statistically significant differences found in their chemical compositions revealed that local raw material sources were selected for the manufacturing of historic brick samples belonging to different cities.
