Availability of sedimentary and volcanic rock deposits on Northeastern Turkey as concrete aggregates
Çavdar, Ahmet; Çavdar, Özlem (Elsevier Ltd, 2024)Turkey has large aggregate deposits; however, these deposits cannot be used effectively due to a lack of controls. This can lead to fatal errors, as in the 6 February 2023 Turkey-Syria earthquakes. The main motivation of ... -
Availability of tuffs from northeast of Turkey as natural pozzolan on cement, some chemical and mechanical relationships
Çavdar, Ahmet; Yetgin, Şükrü (Construction and Building Materials, 2007-12)At Northeast of Turkey, it is possible to find plenty of volcanic origin rocks and rich natural pozzolan beds. In this study, the pozzolanic activities of six types of different tuff samples taken from Trabzon and Bayburt ... -
Beton Basınç Dayanımının Yapay Sinir Ağları İle Tahmini
Albayrak, Selahattin; Çavdar, Ahmet; Bingöl, Şinasi (iseaia 2013 KKTC, 2013)Betonun homojen olmayan yapısı nedeniyle dayanımının ve kalitesinin yerinde kontrol edilmesi oldukça zordur. Bu sebeple, betonun mekanik özelliklerinin yerinde tespitinde tahribatsız yöntemler kullanılabilmektedir. Ancak ... -
Effects of random material and geometrical properties on structural safety of steel–concrete composite systems
Çavdar, Özlem; Bayraktar, Alemdar; Çavdar, Ahmet (INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN BIOMEDICAL ENGINEERING, 2011)A stochastic finite element-based algorithm for probabilistic analysis of structural systems made of composite sections with random material and geometrical properties under earthquake forces is proposed in this paper. ... -
The effects of the fiber contents on the mechanic properties of the adobes
Yetgin, Şükrü; Çavdar, Özlem; Çavdar, Ahmet (Construction and Building Materials, 2008-03)In this study, compression and tensile tests were conducted for five different adobe mixtures. The important part of this study consisted of uniaxial compressive tests done with natural fiber mixtures. Thus, the results ... -
Evaluation of Relationship between Cement Composition and Abrasion Resistance by Using Artificial Neural Network
Çavdar, Ahmet; Albayrak, Selahattin; Yetgin, Şükrü (9th International Congress on Advances in Civil Engineering, 2010-09-27)The abrasion resistance of a concrete and/or cement mortar is changing depending on some properties like compressive strength, matrix structure, gap ratio, aggregate type. On the other hand cement composition has also an ... -
Investigation of Freeze-Thaw Effects on Mechanical Properties of Fibre Reinforced Cement Mortars, (ISI), Volume 58, March 2014, Pages 463-472.
Çavdar, Ahmet (Composites Part B: Engineering, 2014-03)Fibers are used for improving some properties of conventional concrete (which is a brittle material) such as tensile strength, abrasion resistance, absorption and crack control. This study investigates the usability of ... -
Perturbation Based Stochastic Finite Element Analysis of the Structural Systems with Composite Sections under Earthquake Forces
Çavdar, Özlem; Bayraktar, Alemdar; Çavdar, Ahmet; Adanur, Süleyman (Steel and Composite Structures, 2008)This paper demonstrates an application of the perturbation based stochastic finite element method (SFEM) for predicting the performance of structural systems made of composite sections with random material properties. The ...
