Dijkhuis, R.J.E. (author)The basis for this research project was that copper is lost in the Leaching Plant of the Nyrstar Budel zinc smelter. In the section of the Leaching Plant copper is lost, iron and aluminium are precipitated. Sampling of this process showed that the removal of copper from the solution is a function of pH and is mainly linked to the removal of...master thesis 2009

Lai, A. (author)Vanadium is an important industrial metal that is mostly used as an alloying element in steel and to a lesser extent in titanium. It is generally produced in combination with other metals such as iron, titanium, and uranium. The typical production method begins with salt roasting of the ore or concentrate to produce a water soluble form of...master thesis 2010

Laging, V.J.W. (author)The metal zirconium (Zr) and its related alloys have high melting points and an excellent resistance to corrosion. Consequently, zirconium is applied in chemical technology and particularly in nuclear reactors. The low neutron-capture cross-section of zirconium, combined with its corrosive resistance, make the metal pre-eminently suitable as...master thesis 2010

Brouwer, D. (author)In this study a industrial survey was performed on the secondary products generated in the Dutch metal industry. From this industrial survey it was concluded that the Dutch metal industry is already far ahead with closing the materials cycle as for almost every product is a processing route to recover its metal content. The residues generated at...master thesis 2010

Aberkrom, K.J. (author)After fifteen years of service, blast furnace #7 at IJmuiden’s Tata Steel operation was blown down on the 31st of August in 2006 for a small repair. The blow down and salamander tap were successfully completed and afterwards the furnace was quenched with water. All remaining liquids are solidified followed by excavation of the remaining skull....bachelor thesis 2011

Boeree, C.R. (author)This report introduces a method for the removal of zinc from aircraft aluminium-alloy scrap. The driving force for this research is the demand from the secondary aluminium industry for a low zinc content in the Al-alloy scrap, and the growing demand for aluminium in the world. Meanwhile large amounts of obsolete aircraft are stored because of...bachelor thesis 2011

Mardones, J.P. (author)This thesis studies the zinc extraction from spinels through hydro and pyrometallurgical processing. Two zinc-bearing spinels are covered: zinc ferrite ZnO·Fe2O3 to a limited extent and gahnite ZnO·Al2O3 as the main subject, compounds which are found naturally on the Earth’s crust as well as in industrial residues from the zinc industry, steel...master thesis 2012

Zhou, T. (author)In some situations, concentrated vorticity which forms a vortical flow is involved in the inflow of a propeller. The impingement of the vortex on the propeller has several detrimental effects, e.g., foreign object damage during ground operation, impact on the propeller performance, unsteady loading on the blade, and tonal noise generation. The...master thesis 2015

Verburg, R.A. (author)At Tata Steel IJmuiden a part of the blast furnace dust is not recycled to prevent too high zinc levels in the blast furnace. Blast furnace dust is first separated from the off-gas into dry dust and sludge. The dry dust is collected in a dust bag and is directly transported to the sinyter plant. Then the sludge is separated by size through...master thesis 2015

Nijgh, M.P. (author)Minor thesis --- Preload loss in pretensioned bolts is an inevitable phenomenon. This thesis focuses on the different causes for bolt relaxation and their relation to joint design. Investigating bolt relaxation is relevant because there is a direct relation between the bolt preload and the resistance of the connection. In order to assess the...student report 2016

Aukselis, A. (author)The Groningen region, in the Netherlands, experiences earthquakes since 1986. These earthquakes are new to the region and the structures built there are not designed for it. Therefore, they pose a great risk for the historical structures and people living in the area. Most of the buildings there are built using masonry and to analyze such...master thesis 2017

Chondrogiannis, K. (author)The aim of this thesis is to investigate the feasibility of determining the preload in bolts in High Strength Friction Grip Conections and performing in situ measurements. The magnitude of the preload is important for the behavior of High Strength Friction Grip Connections, as it defines the fatigue life of the connection and limits the...master thesis 2017

Dhanmeher, Saurabh (author)Uncertainties regarding structural safety of reinforced concrete structures may warrant a need for a detailed assessment. A detailed assessment using nonlinear finite element analysis is one of the alternatives which could help in decision-making about maintaining, upgrading or even demolishing and rebuilding of the structure. A reliable...master thesis 2017

Zarate Garnica, Gabriela (author)Digital Image Correlation analysis is performed to obtain measurements of the crack kinematics of four reinforced concrete beams without shear reinforcement. The results are used to implement the critical shear displacement theory. This new theory proposes that the opening of the critical inclined crack can be considered as a lower bound for the...student report 2018

Sun, Yubo (author)Considered as an effective real-time monitoring tool, Acoustic Emission (AE) measurements is a promising technology for reinforced concrete (RC) structures. However, its application on real RC structures is still limited. Due to the lack of knowledge on the crack induced acoustic emission in large scale structures.<br/><br/>The aim of this study...student report 2018

Naderi, Nader (author)Highway bridges along the coast and small river bridges in mountainous regions can be submerged during storm surges or strong rainfall events, respectively. Loss of serviceability during these conditions can dramatically hamper the evacuation plan and the capacity for emergency transportation, thus it is essential to ensure the stability of...master thesis 2018

Kotnis, Joanna (author)Cobalt is one of the most important critical raw materials for emerging technologies. There are many incentives for analysis of this metal, from increasing demand for rechargeable batteries, rising prices and social issues involved. This paper is the first attempt to perform a substance flow analysis of cobalt at a city level. The analysis...master thesis 2018

Zarate Garnica, Gabriela (author)Shear failure is one of the most critical failure modes of reinforced concrete members, especially for those without shear reinforcement. Despite the extensive research programs in the last decades, there is still no general agreement on a rational theory to assess their shear capacity. In the recent years, researchers have focused on developing...master thesis 2018

Presvyri, Stamatia (author)The shear capacity of concrete members is a major challenge of structural concrete research through the years. Many theoretical models have been developed and various experiments have been performed, focusing on the accurate prediction of the shear behavior. Many of the available theoretical models assume that a large contribution of the shear...master thesis 2019
