The physics of cement cohesion
Abhay Goyal, Ivan Palaia, Katerina Ioannidou +5
Cement is one of the most produced materials in the world. A major player in greenhouse gas emissions, it is the main binding agent in concrete, to which it provides a cohesive str…
Creep in reactive colloidal gels: a nanomechanical study of cement hydrates
Michael Haist, Thibaut Divoux, Konrad J. Krakowiak +4
From soft polymeric gels to hardened cement paste, amorphous solids under constant load exhibit a pronounced time-dependent deformation called creep. The microscopic mechanism of s…
Multiscale Poromechanics of Wet Cement Paste
Tingtao Zhou, Katerina Ioannidou, Franz-Josef Ulm +2
Capillary effects such as imbibition-drying cycles impact the mechanics of granular systems over time. A multiscale poromechanics framework was applied to cement paste, that is the…
Phase separation of stable colloidal clusters
Thomas Petersen, Martin Z. Bazant, Roland J. M. Pellenq +1
This Article presents a nonequilibrium thermodynamic theory for the mean-field precipitation, aggregation and pattern formation of colloidal clusters. A variable gradient energy co…
Velocity Statistics of the Nagel-Schreckenberg Model
Nicolas Bain, Thorsten Emig, Franz-Joseph Ulm +1
The statistics of velocities in the cellular automaton model of Nagel and Schreckenberg for traffic are studied. From numerical simulations, we obtain the probability distribution…
Topological Origin of Fracture Toughening in Complex Solids: the Viewpoint of Rigidity Theory
M. Bauchy, M. J. Abdolhosseini Qomi, C. Bichara +2
In order to design tougher materials, it is crucial to understand the relationship between their composition and their resistance to fracture. To this end, we investigate the fract…
