Alkharraa, H.S.H. (author)Oil exploitation of tight reservoirs has gained significant importance lately. Some researchers have defined tight reservoirs as those characterized with permeability lower than 0.1 mD. However, permeability is an absolute value, and tight reservoirs have complex pore systems that require a detailed geological and petrophysical rock...doctoral thesis 2024

Pearson, M. (author), Casson, M. (author), Millar, I. (author), Charton, R.J.G. (author), Redfern, J. (author)Climate change directly impacts the source, mode and volume of sediment generation which can be observed in the rock record. To accurately model source to sink systems, in addition to hinterland geology, tectonics and transport distance, a thorough comprehension of the climate is essential. In this study we evaluate the role of climate on...journal article 2024

Rahmani, Hossein (author)The economic and environmental advantages of extrusion-based 3D concrete printing have made it a frontrunner in large-scale buildings. Nonetheless, this approach suffers from a contradictory rheological requirement and a high percentage of Portland cement (PC) in its mixture, which challenges its sustainability. It is claimed that the addition...master thesis 2023

Pedrotti, Matteo (author), Dieudonné, A.A.M. (author), Dijkstra, J. (author), Musso, Guido (author), Hattab, Mahdia (author), Viggiani, Gioacchino (author)The importance of physico-chemical processes at the particle scale for the engineering scale behaviour of fine-grained geomaterials is undisputed. Yet, despite great advances in the discipline, experimental evidence that fully resolves the clay micromechanics i.e. linking the evolving microstructure and interparticle actions under loading, is...conference paper 2023

Konstadinou, M. (author), Herrier, G. (author), Stoutjesdijk, T. (author), Losma, F. (author), Zwanenburg, C. (author), Dobbe, R. (author)This study aimed to assess the suitability of lime treatment for use in dikes in the Netherlands. The effect of this technique on the behavior of a Dutch clay was addressed by comparing the detailed response of lime-treated and natural samples at different lime contents (1.25% and 2.25%) and curing periods. A series of laboratory tests...journal article 2023

Koohmishi, Mehdi (author), Guo, Y. (author)The occurrence of ballast contamination or fouling frequently results in a sudden decline in the capacity of railway ballasted tracks. Considering the various sources of ballast fouling, clay is the most severe one for causing a drastic reduction in the drainage capacity of the ballast layer. In the current study, we utilized a large-scale...journal article 2023
