Roeplal, R.N. (author), Pang, Y. (author), Schott, D.L. (author)Bed permeability is a crucial factor in blast furnace performance which depends on the material distribution achieved through charging. Since a homogeneous bed of pellet and sinter is recommended, it is crucial to understand whether segregation of the pellet-sinter mixture occurs during charging. The Discrete Element Method is useful in this...journal article 2024

Teixidó, Helena (author), Caglar, Baris (author), Michaud, Véronique (author)We seek to address how air entrapment mechanisms during infiltration are influenced by the wetting characteristics of the fluid and the pore network formed by the reinforcement. To this end, we evaluated the behavior of two model fluids with different surface tensions, infiltrating three carbon fiber reinforcements, by means of X-ray...journal article 2023

Belo Gomes Brito, C. (author), Teuwen, Julie J.E. (author), Dransfeld, C.A. (author), Villegas, I.F. (author)This paper evaluates the potential of changing the welding force and the compliance of the energy director (ED) to reduce the effects caused by misaligned adherends, which were: increased through-thickness heating, reduced size of welded area and increased heating time. In the methodology that was followed, we welded adherends misaligned by...journal article 2023

He, S. (author), Liang, M. (author), Yang, En-hua (author), Schlangen, E. (author)The properties of the interfacial transition zone (ITZ) between microfiber and cement-based matrix are of primary significance for the overall behavior of strain hardening cementitious composites (SHCCs). However, due to the relatively small diameter of polymeric microfibers (e.g., PVA fiber), it is technically difficult to obtain...book chapter 2023

Jolly, Mark (author), Katgerman, L. (author)Over the last 4 decades, remarkable progress has been made in the modelling of casting processes. The development of casting models is well reflected in the proceedings of the 15 Modelling of Casting, Welding and Advanced Solidification Processes (MCWASP) conferences that have been held since 1980. Computer simulations have enabled a better...journal article 2022

Oesch, Tyler (author), Weise, Frank (author), Marx, Heidi (author), Kositz, Mario (author), Huenger, Klaus-Juergen (author)Intensified Alkali-Silica Reaction (ASR) damage has occurred on German roadways in recent years, leading to requirements for compulsory pre-construction investigation of aggregate alkali sensitivity using concrete tests with external alkali supply. However, since these tests are time-consuming and cost-intensive, there is interest in replacing...conference paper 2021

Xu, Zhenhai (author), Gao, Jianming (author), Chen, Fei (author)Cement-based materials in sulfate rich areas will suffer from serious corrosion after semi-immersion. To study the degradation of cement mortars with different water cement ratio (w/c) partially exposed to sulfate solution, the mass change were employed to reveal damage progress. Moreover, porosity, erosion products and SO2 4 - content were...conference paper 2021

Tavasoli, S. (author), Breit, W. (author)The effect of type of activator on porosity and CO2 penetration of the alkali activated ground granulated blast furnace slag (GGBS) mortar is an important behavior which is required for designing a durable concrete mixture. This research article investigates the influence of three types of activators consisting of NaOH, Na2.nSiO2 and K2.nSiO2 on...conference paper 2021

Höller, L. (author)The great number of actors in port city regions, such as port authorities, municipalities, national governments, private companies, societal groups, and flora and fauna, need to develop shared visions. Collaborative approaches that focus on combined values can help achieve long-term resilience and enable a sustainable and just coexistence of...journal article 2021

(author)Grain-coating chlorite preserves porosity and permeability through the inhibition of quartz cement whereas pore-filling chlorite blocks pore-throats and diminishes reservoir quality. The aim of this study is to determine the origin and principal mechanisms which govern the distribution of grain-coating and pore-filling chlorite in Jurassic...journal article 2021

Lubelli, B. (author), Nijland, Timo G. (author), van Hees, R.P.J. (author)Compatibility of repair materials in conservation is a widely desired goal, but difficult to achieve. In this research, the compatibility of four commercial stone repair mortars, commonly used in conservation practice in the Netherlands and neighbouring countries, is discussed. In order to do so, they have been characterized in laboratory....journal article 2021

Ažman Momirski, Lucija (author), van Mil, Yvonne (author), Hein, C.M. (author)Ports are clearly demarcated structures on land and water. They are fenced in, easily recognizable on satellite and orthophoto images, and they have specific functions. This apparent clarity of ports, their function and outline, in relation to nearby urban and rural areas, becomes more complex when explored through the lens of land use, that is...journal article 2021

Mendonck, Michiel (author), Aparicio, Sofía (author), Díaz, Cristóbal González (author), Hernández, Margarita G. (author), Caro, Guillermo M.Muñoz (author), Anaya, José Javier (author), Cazaux, S.M. (author)This work studies ultrasonic propagation in liquid and ice water drops. The effect of porosity on attenuation of ultrasonic waves in the drops is also explored. The motivation of this research was the possible application of ultrasonic techniques to the study of interstellar and com-etary ice analogs. These ice analogs, made by vapor...journal article 2021

Hein, C.M. (author)The introduction to this thematic issue on port city porosity sets the stage for the study of port city territories as a particular type of space, located at the edge of land and sea, built, often over centuries, to facilitate the transfer of goods, people, and ideas. It argues that the concept of porosity can help conceptualize the ways in...contribution to periodical 2021

Krishnasamy, J. (author)Thermal Barrier Coating (TBC) systems are protective layers applied to critical structural components of gas turbines operating at high-temperature. A typical TBC system consists of three different layers, namely a ceramic Top Coat (TC), an active Thermally Grown Oxide (TGO) layer and a metallic Bond Coat (BC). The outer ceramic TC that protects...doctoral thesis 2020
