Improvement of expansive soils by using cement kiln dust
Yılmaz, Mehmet Kağan; Çokça, Erdal; Department of Civil Engineering (2014)
Expansive soils are a worldwide problem that poses several challenges for civil engineers. Such soils swell when given an access to water and shrink when they dry out. The most common and economical method for stabilizing these soils is using admixtures that prevent volume changes. In this study, effect of using cement kiln dust (CKD) in reducing the swelling potential was examined. The expansive soil was prepared in the laboratory by mixing kaolinite and bentonite. Cement kiln dust (CKD) was added to the s...
Improvement of an Extremely Highly Plastic Expansive Clay with Hydrated Lime and Fly Ash
Unver, Inci Sut; Lav, Musaffa Ayşen; Çokça, Erdal (2021-04-01)
In this study, extremely highly plastic soil samples were collected from clay deposits in the Akyurt district of Ankara (Turkey), near Esenboga Airport. Hydrated lime and fly ash were applied as chemical stabilizers. The clay samples were mixed with a stabilizing agent considering the dry weight (lime content: 1%, 3%, 5%, 7%, and 9%; fly ash content: 5%, 10%, 15%, 20%, and 25%). The engineering properties of the improved soil samples were determined via laboratory tests. The changes in engineering propertie...
Improvement of the electric field distribution in the medium voltage gas insulated inductive voltage transformers
Var, Melih; Keysan, Ozan; Department of Electrical and Electronics Engineering (2017)
IVoltage transformers are commonly used in medium voltage systems for both protection and measurement purposes. These transformers are designed to satisfy the mandatory IEC requirements at the lowest possible cost. The average life expectancy of such transformer is about 20 years, reliability and robustness are of the utmost importance. The main cause of failure during rated operation is the deterioration of the solid insulation by partial discharges. Partial discharges, unless there is a manufacturing erro...

Improvement of Expansive Soils by Using Phosphogypsum
Çokça, Erdal (null; 2018-09-14)
Expansive soils are an extensive trouble which triggers many challenges for civil engineers. Such soils have either swelling potential or shrinking potential under changing moisture conditions. Admixture stabilization is the most economical and efficient method for prevention of volume changes of these soils. In literature, studies related to remediation of expansive soil are very restricted. In this study the effect of phosphogypsum (PG) in reducing the swelling potential is examined. The expansive soil wa...
