Shakeel, A. (author), Kirichek, Alex (author), Chassagne, C. (author)Kaolinite suspensions are known to have quite fast settling behaviour and Newtonian character, particularly at low concentrations, due to the non-swelling nature of their constitutive particles. On the other hand, bentonite is known for its swelling and interacting nature, which leads to the formation of a network structure, even at low...journal article 2021

Cai, Yuxin (author), Liu, Qing feng (author), Yu, Linwen (author), Meng, Zhaozheng (author), Hu, Zhe (author), Yuan, Qiang (author), Šavija, B. (author)Fresh concrete needs vibration to compact, fill the mould and reach a dense state. During the compaction process, coarse aggregates (CAs) tend to settle, affecting the homogeneity and eventually the long-term durability of hardened concrete. In this study, a 3-D, multi-phase numerical model for fresh concrete is developed for better...journal article 2021

(author), Li, Mingliang (author), Xu, Jian (author)Lignin, as a major waste from biofuel and paper industries, could be utilized as a modifier to enhance the relevant performance of bitumen. However, the effects of lignin on the thermodynamics properties and molecular structure of bitumen are rarely studied. Meanwhile, the potential modification mechanism of lignin modified bitumen is still...journal article 2021

Kirichek, Alex (author), Rutgers, Ronald (author)As regular maintenance and relocation of sediment deposits are highly expensive, Port authorities seek more efficient solutions for reducing the costs and CO2 emissions of maintenance dredging. One solution, water injection dredging (WID), is carried out for maintaining the sediment deposits which predominantly consist of clay and silt. WID has...journal article 2020

Shakeel, A. (author), Farooq, U. (author), Chassagne, C. (author)Oil/water emulsions are usually stabilized either by interfacial modification using nanoparticles and surfactants (stated as pickering emulsion or bijels) or by bulk stabilization with the help of low‐molecular‐weight or polymeric gelators (known as bigels) in response to some external stimuli (e.g., pH, temperature). Both these approaches...journal article 2020

Lin, P. (author), Huang, Weidong (author), Liu, X. (author), Apostolidis, P. (author), Wang, H. (author), Yan, Chuanqi (author)One of the most widely used polymer-based modifiers in asphalt binders is styrene–butadiene–styrene (SBS), which results in binders of increased modulus, strength, toughness, and resistance to permanent deformation. These properties are further improved with the increase of SBS polymer content in asphalt binders, producing binders such as high...journal article 2020

Shakeel, A. (author), Kirichek, Alex (author), Chassagne, C. (author)Yield stress materials have a wide range of commercial applications. Yet, the suitable way of determining the yield stress values of a given material has been the subject of many studies and debates. Yield stresses are dependent on the material (shear) history and composition, which implies that robust protocols should be developed to study...journal article 2020

Lampaert, S.G.E. (author), van Ostayen, R.A.J. (author)The rheological behavior of many lubricants used in hydrodynamic bearings can reasonably be modeled using the Bingham plastic material model. This behavior is characterized by a strong discontinuity, from a pure solid state to a viscous fluid state depending on the local shear stress. In literature three methods have been presented to model a...journal article 2020
