Designing and transforming yield-stress fluids
Current Opinion in Solid State and Materials Science, 2019 We review progress in designing and transforming multi-functional yield-stress fluids and give a perspective on the current state of knowledge that supports each step in the design process.

Darcy’s Law for Yield Stress Fluids [PDF]
Physical Review Letters, 2019 Predicting the flow of non-Newtonian fluids in porous structure is still a challenging issue due to the interplay betwen the microscopic disorder and the non-linear rheology. In this letter, we study the case of an yield stress fluid in a two-dimensional structure.

Journal of Rheology, 2019 Normal stresses in complex fluids lead to new flow phenomena because they can be comparable to, or even larger than, the shear stress. In addition, they are of paramount importance for formulating and testing constitutive equations for predicting nonviscometric flow behavior.

CivilEng, 2021 Alkali-activated materials have the potential to replace Portland cement in certain applications. To better understand these binders’ properties, it is relevant to study their rheological behaviour at early ages, like in the case of Portland cement paste.

Optimal cement paste yield stress for the production of stable cement foams [PDF]
Cement and Concrete Research, 2019 Production of morphology-controlled cement foams remains challenging, mainly due to bubble stability issues during cement setting. The use of cement paste with high yield stress is expected to promote stability by damping intrinsic bubble kinetics.

Effect of Plasticizer on Hydration and Rheological Behavior of Cement Pastes
CivilEng, 2022 Lignosulfonate-based admixtures (LS) obtained from sulfite pulping processes were the first dispersants added as a water-reducer to concrete. Less effective than the latest superplasticizers, the low cost and low environmental footprint of LS continue to

Yield Stress Aging in Attractive Colloidal Suspensions [PDF]
Physical Review Letters, 2022 We investigate the origin of yield stress aging in semi-dense, saline, and turbid suspensions in which structural evolution is rapidly arrested by the formation of thermally irreversible roll-resisting interparticle contacts. By performing optical tweezer (OT) three-point bending tests on particle rods, we show that these contacts yield by overcoming a
