A Multi-scale approach to characterization of volcanic natural pozzolans/ Sassani, Alireza; Turanlı, Lütfullah; Meral, Çağla; Department of Civil Engineering (2014) Three types of volcanic rocks, namely perlite, a zeolite-rich volcanic tuff and a feldspar-rich volcanic tuff were selected to represent the general group of Volcanic Natural Pozzolans (VNPs). The target group was those volcanic natural pozzolans which intrinsically possess pozzolanic properties, i.e. do not require heat-treatment to obtain pozzolanic reactivity. X-ray Fluorescence (XRF), Powder X-Ray Diffraction (XRD), Blaine air permeability test, Laser diffraction, thermogravimetry (TGA), solid-state 29S...
A Study on optimum layout of drainage gallery for concrete dams Daghestani, Tameem; Yanmaz, Ali Melih; Çalamak, Melih; Department of Civil Engineering (2018) Dams are generally massive structures retaining a large amount of water. Any failure could lead to a disaster. Therefore, keeping the dam within the required safety margins and maintaining those conditions is of the utmost importance. A gravity dam is held in place by its own weight. Uplift pressure reduces the effective weight of the dam, thus reducing its safety. Hence reducing the effect of uplift could have significant results in increasing the safety of the dam. In this study, the optimum location of t...
An Experimental and numerical study on the combustion characteristics of pool fires in tunnels Shafee, Sina; Yozgatlıgil, Ahmet; Department of Mechanical Engineering (2017) This work presents the results of experimental and numerical analysis on tunnel fires in an attempt to improve existing knowledge on the fire dynamics and related safety measures in various tunnel fire scenarios. Results are grouped into four parts in which the effects of tunnel wall coating, inclination, tunnel obstruction and existence of secondary fire source in close vicinity were investigated on tunnel fire characteristics. A 1/13 longitudinally ventilated scaled tunnel model constructed based on Froud...
An industrial comparative study of cement clinker grinding systems regarding the specific energy consumption and cement properties Hoşten, Çetin; Fidan, Berkan (2012-05-01) This paper is concerned with a comparative analysis of modern cement grinding systems, namely, combined grinding (Comflex (R)), high-pressure roll mill (HPRM) grinding, and horizontal roller mill (Horomill (R)) grinding. Cement production trials were run with these grinding systems in the same cement plant by using the same clinker/gypsum feed to produce cements of almost identical chemical compositions and similar Blaine fineness values of about 3600 cm(2)/g. The grinding systems were compared in terms of ...
