Prevention of Wave Propagation via Circular Arrangement of Seismic Metamaterials Formed with Concrete Piles
Kaçın, Selçuk; Özturk, Murat; Sevim, Umur Korkut; Karaaslan, Muharrem; Akgöl, Oğuzhan; Özer, Zafer; Demirci, Mustafa; Ünal, Emin; Mert, Bayram Ali; Alkurt, Maide Erdoğan; Alkurt, Fatih Özkan; Başar, Mustafa Tunahan (MDPI, 2023)It is known that the low frequencies of seismic surface waves have a destructive effect. The main purpose of seismic metamaterials is to protect structures from seismic waves at low frequencies, especially in a wide band. ... -
Production of new electromagnetic wave shielder mortar using waste mill scales
Öztürk, Murat; Depci, Tolga; Bahçeci, Ersin; Karaaslan, Muharrem; Akgöl, Oğuzhan; Sevim, Umur Korkut (Elsevier, 2020)Electromagnetic (EM) wave shielder mortar can be produced by mixing cement, natural limestone, tap water with mill scale (mill scale-I and mill scale-II) which is one of the biggest disposal area problems of the iron-steel ... -
Properties of Slightly Alkali-Activated Electric Arc Furnace Slag Concretes and Statistical Evaluation
Bankir, Müzeyyen Balçıkanlı; Sevim, Umur Korkut; Arsoy, Ahmet (Springer, 2022)Electric arc furnace slag (EAFS) is a material that emerges as a by-product in iron and steel plants and is in need of evaluation. To ensure its recovery by using it in concrete production, it was replaced 10%, 20% and 30% ... -
