Öğütülmüş perlit içeren bağlayıcıların alkali-silika tepkimesine etkilerinin ve kimyasal aktivasyon potansiyellerinin incelenmesi

Alkali-silica rectivity and activation of ground perlite-containing cementitious mixtures Ünsal Sağlık, Aslı; Erdoğan, Sinan Turhan; Department of Civil Engineering (2009) Perlite is a volcanic mineral. The latest investigations on ground perlite showed that it is suitable for pozzolanic usage. Thus, it is of vital importance especially for countries rich in perlite such as Turkey. The aim of this study is to investigate the advantages and problems associated with using perlite in concrete and to identify accurate methods and amounts of use for producing durable cementitious mixtures. Within the scope of this study, the alkali-silica reactivity of perlite containing cementiti...
Utilization of GGBFS blended cement pastes in well cementing Alp, Barış; Yaman, İsmail Özgür; Akın, Serhat; Department of Cement Engineering (2012) In well cementing, the cement slurry is exposed to the conditions far different than those of ordinary Portland cement (PC) used in construction. After placement, hardened cement paste should preserve integrity and provide zonal isolation through the life of the well. American Petroleum Institute (API) Class G cement is the most common cement type used in various well conditions. Class G cement has a high degree of sulfate resistance which makes it more stable than PC when subjected to the compulsive well c...
A proverb learned is a proverb earned: future English teachers' experiences of learning english proverbs in Anatolian Teacher Training High Schools in Turkey Can, Nilüfer; Hatipoğlu, Çiler; Department of English Language Teaching (2011) This thesis investigates future English teachers’ experiences of learning English proverbs in Anatolian Teacher Training High Schools (ATTHS) in Turkey. In order to reveal the situation about proverb teaching in English language classrooms in ATTHS, students’ opinions are sought and coursebooks are analysed. In doing this, this study aims to find out EFL teacher trainees’ attitudes towards learning and teaching English proverbs, their conceptualization of proverbs, their thoughts about their knowledge and u...
A systematic study of probabilistic aggregation strategies in swarm robotic systems Soysal, Onur; Şahin, Erol; Department of Computer Engineering (2005) In this study, a systematic analysis of probabilistic aggregation strategies in swarm robotic systems is presented. A generic aggregation behavior is proposed as a combination of four basic behaviors: obstacle avoidance, approach, repel, and wait. The latter three basic behaviors are combined using a three-state finite state machine with two probabilistic transitions among them. Two different metrics were used to compare performance of strategies. Through systematic experiments, how the aggregation performa...
Evolving aggregation behaviors for swarm robotics systems: a systematic case study Bahçeci, Erkin; Şahin, Erol; Department of Computer Engineering (2005) Evolutionary methods are shown to be useful in developing behaviors in robotics. Interest in the use of evolution in swarm robotics is also on the rise. However, when one attempts to use artificial evolution to develop behaviors for a swarm robotic system, he is faced with decisions to be made regarding some parameters of fitness evaluations and of the genetic algorithm. In this thesis, aggregation behavior is chosen as a case, where performance and scalability of aggregation behaviors of perceptron control...
