Microstructural developments of limestone calcined clay cement (LC3) pastes after long-term (3 years) hydration

Karen Scrivener, Franco Alberto Zunino Sommariva

LC3 is one of the most promising alternatives for a high-performance blended cement with a significantly lower clinker content and with potential for worldwide adoption. For this reason, understanding its long-term performance is relevant to ensure service ...

Mechanical and hydraulic transport properties of transverse-isotropic Gneiss deformed under deep reservoir stress and pressure conditions

Marie Estelle Solange Violay, Mateo Alejandro Acosta

In central Europe, many geo-energy reservoirs have revealed to be hosted in transverse isotropic crystalline rock, where the rock's mechanical and hydraulic transport properties are poorly constrained. Here, we performed triaxial experiments on Cresciano G ...

Variations in elastic and electrical properties of crustal rocks with varying degree of microfracturation

Marie Estelle Solange Violay, Lucas Xan Pimienta, Luis Felipe Orellana Espinoza

This work aims at investigating the effect of varying degrees of microfracturing on the joint elastic and electrical transport properties of rocks. Different crustal rocks were subjected to Thermal Treatment, expected to induce microfracturing, up to diffe ...

Experimental results of gravity currents travelling over a fissured bed

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo

Gravity currents are geophysical flows having large impact on human life and on the environment. The need to prevent and mitigate their negative consequences justifies the multitude of studies carried out to understand their physics. However little has bee ...

Experimental study on forces exerted on buildings with openings due to extreme hydrodynamic events

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

Previous studies and field surveys showed that specific structural designs can decrease the load on free-standing buildings along the coast, providing safer vertical shelters. This experimental study investigated the effect of openings in buildings (window ...

Porosity evolution at the brittle-ductile transition in the continental crust: Implications for deep hydro-geothermal circulation

Marie Estelle Solange Violay, Mateo Alejandro Acosta, Michael Heap

Recently, projects have been proposed to engineer deep geothermal reservoirs in the ductile crust. To examine their feasibility, we performed high-temperature (up to 1000 degrees C), high-pressure (130 MPa) triaxial experiments on granite (initially-intact ...

Gestaltung effizienter Geschiebesammler anhand physikalischer Modellversuche mit Fallbeispiel [Design of efficient sediment traps based on physical experiments with case study]

Anton Schleiss, Giovanni De Cesare, Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt

In den vergangenen Jahren haben Hochwasser im Alpenraum die Notwendigkeit von Schutz-maßnahmen vor allem auch auf lokaler Ebene eindringlich in Erinnerung gerufen. Das große Geschiebetransportpotential von Wildbächen kann zu der Zerstörung ganzer Ortschaft ...

Pore structure evolution of compacted granular bentonite during wetting and drying cycles

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

Deep geological repositories are considered as suitable solutions for the disposal of high level nuclear wastes. In several repository concepts (e.g. in Spain and Switzerland), bentonites are selected as the main component of the engineered barrier to be p ...

Water retention behaviour and microstructural evolution of MX-80 granular bentonite during wetting and drying cycles

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

MX-80 bentonite used in engineered barrier systems would be subjected to wetting and drying cycles. To assess the response of the material under such circumstances, a comprehensive experimental characterisation of the water retention behaviour of compacted ...

Analysis of the compaction phenomena due to the water injection in reservoirs with a three-phase geomechanical model

Lyesse Laloui, Mathieu Nuth

In the coastal regions, the land subsidence due to the industrial pumping of underground fluids such as methane is documented by the means of in situ surveys. The laboratory characterization of the gas bearing formations has also been published, which comp ...

Permeability of deformable soft aggregated earth materials: From single pore to sample cross section

Dani Or

[1] Fluid flow in deformable porous media is of interest in many areas of hydrology, geophysics, and environmental engineering at scales ranging from individual pore to field scale. With increasing interest in pore-scale hydraulics, there is also the need ...

Size and shape evolution of pores in a viscoplastic matrix under compression

Dani Or

The frequent use of soils and earth materials for hydraulic capping and for geo-environmental waste containment motivated our interest in detailed modelling of changes in size and shape of macro-pores to establish links between soil mechanical behaviour an ...
