Anadolu Hisarı Harçlarının Fiziko-Kimyasal ve Petrografik Özelliklerinin İncelenmesi


This study aims to analyze petrographical, chemical, physical and mechanical properties of specific lime mortars used during the construction of the historical Anatolian Fortress. Chemical composition of the mortars is identified by ICP analysis, whereas their mineralogical structure is determined by XRD analysis. Petrographical analysis of thin section samples is executed under polarizan microscope. Mechanical tests are performed with the samples adjusted to appropriate dimensions. Ultrasound speed of samples is measured before mechanical experiments and their dynamic elasticity modules are calculated on the basis of this data. In accordance with data obtained, mortars of Fortress consist of lime binder with a rate of 30-40% and resting part includes various natural and artificial aggregates. Mortars have hydraulic features and associated feature of pink mortars is achieved by means of brick dusts added. As for cream colored mortars, it is anticipated that this feature is obtained by means of cystic and tuffic materials. Protein is identified in some mortar samples during spot tests. This identification indicates that organic additives are used during production of mortars. In addition, mortars have superior characteristics in mechanic sense. Data obtained also represent a guide for new materials to be used during repair works
