Effect of ground perlite incorporation on the performance of blended cements
Erdem, T. K.; Akgül, Çağla; Tokyay, Mustafa; Erdoğan, Turhan Y. (2007-06-13)
Perlite is a volcanic rock that contains relatively high amounts of SiO2 and Al2O3. Due to its proper chemical composition and glassy structure, it can be used as a pozzolanic addition in blended cements. In this study, ground perlite was used as a cement replacement material in blended cements. Several mortar mixes were prepared to investigate the performance of those cements. The results showed that perlite incorporation caused early age strength losses when compared to the control mortars containing only...
The effect of representative training dataset selection on the classification performance of the promoter sequences
YAMAN, Ayse Gul; Can, Tolga (2011-05-05)
Promoter prediction is an important task for genome annotation. The aim of this study is to build a classification method for promoter prediction. Base-stacking energy values of dinucleotides are used for feature extraction and Support Vector Machines (SVMs) are used for classification. Human genome promoter sequences are used as the positive training data and three types of datasets are prepared as the negative data including intergenic and transcribed sequences. Best results are achieved by selecting equa...
Effect of alkali-silica reaction expansion on mechanical properties of concrete
Hafçı, Alkan; Turanlı, Lütfullah; Department of Civil Engineering (2013)
Alkali-silica reaction (ASR) is a chemical deterioration process which arises in concrete due to reactive aggregate from its constituent, sufficient alkalis from cement or external resources and humidity about 85%. ASR gel, formed by the reaction, absorbs water and expands so that it causes expansion and cracking in concrete. ASR has detrimental effects on mechanical properties of concrete. Therefore, ASR which is a long and a constantly progressive reaction may become a threat to the safety of concrete str...
Properties and hydration of cementitious systems containing low, moderate and high amounts of natural zeolites
Uzal, Burak; Turanlı, Lutfullah; Department of Civil Engineering (2007)
The extent of the benefits provided by use of SCMs in cementitious systems increases as their percentage amounts in total binder increases. However, the proportion of SCMs in cementitious systems is limited, especially for natural pozzolans, by some factors such as increase in water requirement and decrease in rate of strength development. Therefore investigations are needed to increase the amount of natural pozzolans in blended cements or in concrete as much as possible without decreasing their performance...
Effects of cast-in-place concrete topping on flexural response of precast concrete hollow-core slabs
Baran, Eray (2015-09-01)
Results of a study focusing on the flexural response of precast prestressed concrete hollow-core slabs with cast-in-place concrete topping are presented. The experimental part of the study included load testing of five precast concrete hollow-core units. The numerically determined flexural response of test specimens was later compared with the experimentally obtained behavior. Results demonstrate that a major composite action is valid between the hollow-core unit and the topping slab under load levels corre...
