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 materials in mortar and plaster samples were investigated by pozzolanic activity tests performed on the aggregates (< 125 mu m) and examining the reaction products formed after immersion of these aggregates in a saturated solution of Ca(OH)(2). Investigated mortar and plaster samples were found to have relatively low bulk density and high effective porosity. Compressive strength values of mortar samples were found to be in the range of 3.92-4.47 MPa. Binder used in the mortar and plaster samples were assessed to be fat lime. Aggregates of the samples smaller than 125 mu m were found to have good pozzolanicity. Formation of pozzolanic reaction products by the reaction of the finer aggregates with Ca(OH)2 were confirmed by the results of SEM-EDX and FTIR analyses.

Consequences of dewatering cement mortars incorporated with ground Bayburt stone Ince, Ceren; Derogar, Shahram (Thomas Telford Ltd., 2018-06-01) The detrimental effects of the rapid dewatering of cement mortars due to the interaction of wet mortar and brick substrate at the freshly mixed state in masonry construction are often addressed in the literature. The desorptivity and hence very high water releasing ability of cement mortars result in a great water loss during dewatering that significantly affects the fresh and hardened state properties of the end product. The paper therefore investigates the possible role of ground Bayburt stone incorporati...
Examining the impact of soluble salts on dolomite deterioration Tavukçuoğlu, Ayşe; Caner Saltık, Emine; Güney, Bilge Alp; Erol, Fatıma; Mısır, Çağkan; Çetin, Özlem; Karahan Dağ, Fulya; Ataklı, Yiğit; Çömez Kutan, Seda; Erdil, Meltem (null; 2016-09-21) Salt weathering is known to be destructive to the historical buildings, which are constructed of porous stone materials. The study has the focus on salt weathering assessment on dolomite, a building stone that has been widely used in Anatolian monuments. The study is composed of laboratory analyses and non-destructive investigation techniques in order to better understand the causes and mechanism of decay. The artificially weathered dolomite samples by salt crystallization cycles were prepared at various st...
Determining the thickness of concrete pavements using the impact-echo test method Aktaş, Can Baran; Yaman, İsmail Özgür; Department of Civil Engineering (2007) Traditionally, destructive methods such as coring are used for the condition assessment of an existing concrete structure. Although these methods may yield valid data about the corresponding concrete section, they are quite expensive and time consuming. More important than these, destructive methods damage the structure being investigated and these points usually become focal points for further deterioration. For all these reasons, only a few samples can be collected from a structure and this results in a p...
Determination Of Asbestos Using As A Construction Material On Public Buildings Between 1960-1980 And Its Importance In Terms Of Medical Geology Dündar Mustafa, Deniz; Toksoy Köksal, Fatma (2021-05-24) Asbest minerallerinin 20. yüzyılın başından itibaren pek çok alanda özellikle de yapı malzemelerinde kullanıldığı bilinmektedir. Fiziksel ve kimyasal özelliklerinin uygunlukları sebebiyle izolasyon amacıyla yaygın olarak yapı malzemelerine katılarak kullanılan asbest türleri, 2003 yılında Dünya Sağlık Örgütü tarafından en önemli kanserojenlerden biri olarak tanımlanmıştır. Ülkemizde kademeli olarak kısıtlanan asbest üretimi ve kullanımı, 2010 yılından itibaren bütünüyle yasaklanmıştır. İnsan sağlığına olums...
Investigation of combustion kinetics of treated and untreated waste wood samples with thermogravimetric analysis Yorulmaz, Sema Yurdakul; Atımtay, Aysel (2009-07-01) In the present study, combustion mechanisms, thermal kinetics, and phases of combustion were investigated for waste wood samples (untreated pine and treated MDF, plywood and particleboard). Waste wood samples were combusted in air at 10, 20 and 30 degrees C/min heating rates in TGA. The results of TG analysis have shown that thermal decomposition of treated samples takes place at lower temperatures as compared to the untreated pine sample because of the catalyzing effects of the chemicals in the samples. Th...
