    NON-DESTRUCTIVE TEST INVESTIGATIONS ON THE DETERIORATION OF ROMAN MAUSOLEUM IN KARADAG CENTRAL ANATOLIA, TURKEY
    (Uk Zhende Publishing Ltd, 2020) Tosunlar, Mehmet Bahadir; Beycan, Arife Deniz Oktac; Korkanc, Mustafa
    The Binbirkilise region has maintained its existence as an important religious and cultural center from the Hittites to the last period of the Eastern Roman Empire. There are many monuments in the region dating back to these periods. Among the region monuments, a Roman mausoleum draws attention along with its construction system and original form. This mausoleum was recently (2015) completely unearthed in the archaeological excavations carried out by the archaeologists of the Karaman Museum. Since then serious deterioration problems started to occur of atmospheric, biological and human origin. Several non destructive techniques (NDT) were applied and relevant measurements undertaken such as; temperature (ST), surface moisture (SM), Schmidt hammer rebound (SHR), and P-wave velocity (Vp) tests, 3D photogrammetry, thin sections, polarizing microscope, XRF analyses, XRD, mainly used to determine the deterioration conditions of building stones on the surface. The NDM innovative approach contributed to the understanding of the deterioration dynamics. It has been determined that a white crust formation on the parts of the monument unearthed by excavations and this crust formation affects the deterioration process of the building stones.

    The Determination of Deteriorations on The Misirlioglu Bridge (Konya, Turkey) by Non-Destructive Techniques (NDT)
    (Selcuk Univ, 2018) Tosunlar, Mehmet Bahadir; Hatir, Mehmet Ergun; Ince, Ismail; Bozdag, Ali; Korkanc, Mustafa
    Transportation has been one of the basic requirements of humanity since the earliest periods of civilization. One of the architectural structures designed to meet this requirement is historic stone bridges. One of the most important stages in these conservation works is the assessment of materials that constitute the structures. Non-destructive testing techniques (NDT) are widely used to obtain qualitative data and also make comparisons. In this study, it was aimed to determine deteriorations on the Misirlioglu Bridge located in Sille settlement of Konya by NDT technique and to form the map from obtained values to perform conservation works. As a result of the analyses performed, considerable deteriorations in the building stones used in the abutments and arches of the structure were determined. Besides, it is detected that uniaxial compressive strength (UCS) value of the fresh samples is high (UCS: 61 MPa) while UCS values of the building stones used at the bridge decrease in the range of low and high (8-51 MPa) due to the atmospheric effects.
