Preparation of pozzolanic lime mortars for repairing limestone of Nemrut Dag Monument

2013-02-01
The aim of this study is to prepare pozzolanic lime mortars to be used for stone repairs such as sticking large detached scales, filling gaps and large cracks in the deteriorated limestone objects of Nemrut Dağ Monument in Adıyaman Turkey. Mortar samples from rubble stone masonry of Kahta Castle, a medieval structure, in close vicinity of the Nemrut Dağ Monument, were investigated to set an example for the preparation of repair mortars. Repair mortar mixtures were prepared by using laboratory grade Ca(OH)2, local river sand and two types of pozzolans; metakaolin and natural trass. Basic physico-mechanical properties of historic mortars and repair mortar cubes after 60 day curing period were determined. Both historic and repair mortars were investigated by optical microscopy and SEM-EDX, XRD, FTIR. Pozzolanic activity of the pozzolans used in this study, fine aggregates of historic mortars and fine aggregates of local river sand were investigated. CSAH and CSH were detected by XRD and SEM-EDX in the repair mortars prepared with added metakolin. After 60 days, the bulk density and effective porosity values of prepared repair mortar cubes were observed to be slightly lower than that of historic mortars. The compressive strength of prepared mortars with added metakaolin were quite near to the compressive strength historic mortars, however their carbonation were not yet completed. The results were further evaluated in comparison with historic mortars and for the preparation of compatible and durable repair mortars.

Investigation of Mortars and Plasters of a Byzantine Church in Southwest Anatolia with Emphasis on Possible Pozzolan Use
CANER, EVİN; Güney, Bilge Alp (Publishing House Technologija, 2018-01-01)
Characterization of mortars and plasters used in historical structures is crucial before conservation interventions in order to propose proper repair materials and avoid any damage caused by material incompatibility. In the present study, mortars and plasters of a Byzantine Church in the ancient city of Stratonikeia dated back to 5th-7th centuries were examined in terms of physical/physico-mechanical characteristics and raw materials used by various analytical techniques. Possible use of pozzolanic material...
Evaluation of seismic resistance of traditional Ottoman timber frame houses
Aktaş, Yasemin Didem; Şahin Güçhan, Neriman; Türer, Ahmet; Department of Architecture (2011)
The aim of this study is to evaluate the seismic resistance of traditional Ottoman timber frame “hımış” structures, which form the major part of Turkey’s cultural heritage, from an engineering point of view. On the other hand, the seismic resistance of traditional Ottoman timber frame structures was not evaluated from an engineering perspective. For the aim of seismic resistance evaluation of traditional Ottoman timber frame houses, the TUBITAK (the Scientific and Technological Research Council of Turkey) p...
REVERSE-ENGINEERING EVALUATION AND MONITORING OF NEMRUT MONUMENTS
Türer, Ahmet; Şahin Güçhan, Neriman (2012-01-01)
The focus of this study is on the Nemrut Dag monuments, which were constructed approximately 2000 years ago at the peak of Mount Nemrut, 2206 meters elevation, are among the most valuable historical heritage sites in Turkey. Since the discovery of Nemrut monuments in 1881, many questions are unresolved, such as how the monuments were destroyed and why the damage level is very different between the symmetric east and west terraces. Natural causes, such as earthquakes, snow, or wind or manmade damages in the ...
Thermal and hygric expansion characteristics of mortars and bricks used in the dome structures of Turkish Baths from 14th and 15th centuries
Güney, Bilge Alp (2015-10-01)
Thermal and hygric expansion characteristics of mortars and bricks from the dome structures of three Turkish Baths from 14th and 15th centuries were investigated. The linear thermal expansion coefficients of the mortars and bricks were determined in the temperature range from -10 degrees C to 50 degrees C and hygric expansion characteristics of the same samples were studied in the relative humidity range from 30% to 80%. The results showed that the thermal and hygric expansion characteristics of mortars use...
Quantitative Infrared Thermography and Ultrasonic Testing for InSitu Assessment of Nemrut Dag Stone Statues
Tavukçuoğlu, Ayşe; Saltık, Emine Nevin (2014-08-01)
The study was focused on the in-situ non-destructive examination of limestone and sandstone statues in Nemrut DaÐ Monument to determine their state of deterioration and the target areas for the application of conservation treatments. The examinations were done by the combined use of quantitative IR thermography (QIRT) and ultrasonic testing supported by the laboratory measurements to obtain standard data from the reference samples. The in-situ QIRT analyses were promising particularly for the detection of d...
