Navigating the Complexities of Multiple Redox State Interactions in Aqueous Systems
Shishir Mundra, Mohit Pundir, Barbara Lothenbach +2
Numerous aqueous systems host elements in multiple redox states, with wide ranging implications such as their influence on the formation/dissolution of minerals, water toxicity, an…
Precipitation of corrosion products in macroscopic voids at the steel-concrete interface -- observations, mechanisms and research needs
Shishir Mundra, Emanuele Rossi, Luka Malenica +2
Macroscopic voids at the steel-concrete interface and their degree of saturation with an aqueous electrolyte are known to play an important role in the corrosion of steel in reinfo…
Towards improved understanding of spontaneous imbibition into dry porous media using pore-scale direct numerical simulations
Luka Malenica, Zhidong Zhang, Ueli Angst
Traditional approaches to mathematically describe spontaneous imbibition are usually based on either macro-scale models, such as Richards equation, or simplified pore-scale models,…
Microscale chemical imaging to characterize and quantify corrosion processes at the metal-electrolyte interface
Cristhiana C. Albert, Shishir Mundra, Dario Ferreira Sanchez +5
We introduce an experimental setup to chemically image corrosion processes at metal-electrolyte interfaces under stagnant, confined conditions relevant in a wide range of situation…
Durability of MgO/hydromagnesite mortars -- Resistance to chlorides and corrosion
Fabio Enrico Furcas, Alexander German, Frank Winnefeld +2
The durability of MgO/hydromagnesite mortars was studied with respect to their corrosion performance and resistance to chloride attack and moisture. MgO/hydromagnesite pastes were…
The influence of silicon on the formation and transformation of corrosion products
Fabio E. Furcas, Shishir Mundra, Barbara Lothenbach +3
Accurate model predictions of corrosion-driven damage in reinforced concrete structures necessitate a comprehensive understanding of the rate of corrosion product formation. Here,…
Three-dimensional characterization of the steel-concrete interface by FIB-SEM nanotomography
Nicolas Ruffray, Ueli M. Angst, Thilo Schmid +2
While it is widely accepted that the steel-concrete interface (SCI) plays an important role in governing the long-term durability of reinforced concrete structures, understanding a…
Nondestructive detection and quantification of localized corrosion rates by electrochemical tomography
Meeke C. van Ede, Andreas Fichtner, Ueli Angst
Localized corrosion is one of the most common causes of early degradation of engineering structures. To non-destructively determine the location, size and rate of localized corrosi…
Mechanism of cathodic protection of iron and steel in porous media
Federico Martinelli-Orlando, Shishir Mundra, Ueli M. Angst
Cathodic protection (CP) was introduced two centuries ago and since has found widespread application in protecting structures such as pipelines, offshore installations, and bridges…
An FFT-based framework for predicting corrosion-driven damage in fractal porous media
Mohit Pundir, David S. Kammer, Ueli Angst
Understanding fracture in cementitious materials caused by the deposition and growth of corrosion products requires scale-bridging approaches due to the large length-scale differen…
Active Interaction Force Control for Contact-Based Inspection with a Fully Actuated Aerial Vehicle
Karen Bodie, Maximilian Brunner, Michael Pantic +5
This paper presents and validates active interaction force control and planning for fully actuated and omnidirectional aerial manipulation platforms, with the goal of aerial contac…
An Omnidirectional Aerial Manipulation Platform for Contact-Based Inspection
Karen Bodie, Maximilian Brunner, Michael Pantic +5
This paper presents an omnidirectional aerial manipulation platform for robust and responsive interaction with unstructured environments, toward the goal of contact-based inspectio…
