Zlopasa, J. (author), Norder, B. (author), Koenders, E.A.B. (author), Picken, S.J. (author)Here we report on a study of a rheological behavior of sodium alginate and montmorillonite suspension. We find that viscoelastic behavior of this suspension is dramatically affected with increasing volume fraction of montmorillonite platelets. Addition of montmorillonite generally leads to gel formation, which is attributed to interactions of...journal article 2016

Tarsi, G. (author), Varveri, Aikaterini (author), Lantieri, Claudio (author), Scarpas, Athanasios (author), Sangiorgi, Cesare (author)Bitumen undergoes ageing, which leads to changes in its chemical and rheological properties, causing it to become harder and more brittle with time. This study aims to compare the effects of different laboratory ageing methods on the chemistry and rheology of three bitumen types: a Pen 40=60, a Pen 70=100, and a polymer-modified bitumen (PmB)...journal article 2018

Thota Radhakrishnan, A.K. (author), van Lier, J.B. (author), Clemens, F.H.L.R. (author)The much over-looked element in new sanitation, the transport systems which bridge the source and treatment facilities, is the focus of this study. The knowledge of rheological properties of concentrated domestic slurry is essential for the design of the waste collection and transport systems. To investigate these properties, samples were...journal article 2018

Shakeel, A. (author), Kirichek, Alex (author), Chassagne, C. (author)Purpose: An innovative way to define navigable fluid mud layers is to make use of their rheological properties, in particular their yield stress. In order to help the development of in situ measurement techniques, it is essential that the key rheological parameters are estimated beforehand. Is there only one yield stress? In which shear rate...journal article 2019

Shakeel, A. (author), Kirichek, Alex (author), Chassagne, C. (author)Mud is a cohesive material which contains predominantly clay minerals, water, organic matter and some amounts of silt and sand. Mud samples can have complex rheological behaviour, displaying viscoelasticity, shear-thinning, thixotropy and yield stress. In this study, influence of organic matter on the rheological behaviour of different mud...journal article 2019

Mahajan, V.V. (author), Mehmood, J. (author), El Hasadi, Yousef M.F. (author), Padding, J.T. (author)The rheology of suspensions of high-inertia (or granular) non-spherical particles characterized by high particle Stokes and Reynolds numbers is rarely investigated. In this study, we investigate the rheology of suspensions of inertial rod-like particles of aspect ratio 4 subjected to shear flow. In particular, the effect of fluid medium (air,...journal article 2019

(author), Moniruzzaman, Muhammad (author)Ionic liquids (ILs) are liquid salts at ambient or lower temperatures and consist of ions and short-lived ion pairs. They are potential alternatives to toxic, hazardous, highly flammable, and volatile solvents for preparing solutions, dispersions, gels, composites, and polymeric melts. ILs have some very interesting and unique characteristics...journal article 2019

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

(author)The characteristics of clayey suspensions, majorly composed of quartz microparticles, in the presence of anionic and cationic polyelectrolytes were investigated using different techniques. A wide range of clay concentrations was used, i.e., from 0.07 to 1000 g/L for different experimental techniques, based on the fact that the clay...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

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

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
