(author), Wang, Xuancang (author), Scarpas, Athanasios (author)Lignin, one of the most abundant natural polymers, has been extensively studied as an additive in bituminous binders. Even though the lignin improves the overall resistance against oxidative aging of bitumen, it could lead to high thermal cracking sensitivity. In this study, a bio-oil (i.e., rapeseed oil) is implemented in lignin-modified...journal article 2022

Shakeel, A. (author), Chassagne, C. (author), Bornholdt, Jasper (author), Ohle, Nino (author), Kirichek, Alex (author)The nautical bottom (i.e., the level at which contact with a ship’s keel causes either damage or unacceptable effects on controllability and manoeuvrability of a ship) should be associated to a measurable physical characteristic. Bulk density is typically used as a criterion for nautical bottom by many ports worldwide. However, the rheological...journal article 2022

Sun, Yubo (author), Tao, Yaxin (author), Rahul, A. V. (author), Ye, G. (author), De Schutter, Geert (author)The rapid workability loss of alkali-activated materials (AAM) has been a major obstacle limiting its onsite application. In this study, two conventional SPs (made of polynaphthalene sulfonate (PNS) and lignosulfonate (LS) salts), which have been reported to be effective in some specific AAM mixtures were separately applied in alkali...journal article 2022

Boschan, J. (author)Systems far from equilibrium have numerous practical uses, but challenge our understanding of their underlying physics. Materials like foams, emulsions, suspensions and granular matter can show liquidlike properties or get trapped in a solidlike jammed state. The phase transition between the flowing and static state is often referred to as the ...doctoral thesis 2021

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

Shakeel, A. (author), Kirichek, Alex (author), Chassagne, C. (author)Mud, a cohesive material, consists of water, clay minerals, sand, silt and small quantities of organic matter (i.e., biopolymers). Amongst the different mud layers formed by human or natural activities, the fluid mud layer found on top of all the others is quite important from navigational point of view in ports and waterways. Rheological...book chapter 2021

Porot, Laurent (author), Chailleux, Emmanuel (author), Apostolidis, P. (author), Zhu, Jiqing (author), Margaritis, Alexandros (author), Tsantilis, Lucia (author)The asphalt industry is constantly working to enhance the performances of asphalt materials, introducing innovative and more sustainable solutions. In this context, the incorporation of materials, such as additives, polymers, is more and more used to improve the properties of neat bitumen. This leads to even more complex bituminous binders,...conference paper 2021

Shakeel, A. (author), Farooq, U. (author), Gabriele, Domenico (author), Marangoni, Alejandro G. (author), Lupi, Francesca R. (author)Background: Polymeric gels, an important class of soft matter systems, are widely used for commercial applications particularly in food products (i.e., saturated fat replacement). The efficiency of the product for a particular application can be directly linked to its rheological signature. However, the rheological imprint of these structured...review 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

Srinivasan, Sudharsan (author), van den Akker, H.E.A. (author), Shardt, Orest (author)Using an immersed boundary-lattice Boltzmann method, we investigated the response of dense granular suspensions to time-varying shear rates and flow reversals. The evolution of the relative apparent viscosity and particle structures was analysed. The concentration of solids (ϕ<sub>v</sub>) and particle Reynolds numbers (Re<sub>p</sub>) were...journal article 2021

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

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).

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
