Fouling-resistant pencil graphite electrode

Sandro Carrara, Francesca Stradolini, Tugba Kilic

A Pencil Graphite Electrode (PGE) is herein disclosed. The electrode is characterized by a reduced content in graphite and an increased content in clay of the composite material composing it compared to the prior art PGEs. In particular, the PGE according ...

Calcined clay limestone cements (LC3)

Karen Scrivener

The use of supplementary cementitious materials (SCMs) to replace part of the clinker in cement is the most successful strategy to reduce CO2 emissions in the global cement industry. However, limited supplies of conventional SCMs make it difficult to take ...

Hazard and risk assessment of earthquake-induced landslides-case study

Landslides as secondary seismic effects are causing some patterns of soil failure that are often considered among the most destructive ones. In fact, the impact from triggered landslides has sometimes exceeded damage directly related to strong shaking and ...

High diffusion barrier and piezoelectric nanocomposites based on polyvinylidene fluoride-trifluoroethylene copolymer and hydrophobized clay

Yves Leterrier, Dragan Damjanovic, Antonia Neels, Sara Dalle Vacche, Alex Dommann, Olha Sereda

Nanocomposites based on polyvinylidene fluoride– trifluoroethylene copolymer and up to 4 vol % of hydrophobized clay nanoparticles are investigated. The structure, piezoelectric properties, and oxygen permeability of solvent cast films are analyzed before ...

Scour depth under pipelines placed on weakly cohesive soils

We here study the scouring processes that evolve around a submarine pipeline placed on a weakly cohesive seabed. We first analyze some laboratory tests carried out by Vijaya Kumar et al. [21], Xu et al. [25] and Zhou et al. [28] that focused on the scourin ...

Pozzolanic reactivity of low grade kaolinitic clays: Influence of calcination temperature and impact of calcination products on OPC hydration

Karen Scrivener

The influence of thermal activation temperature in the pozzolanic reactivity of low grade kaolinitic clay and the impact of calcination products in OPC hydration are assessed in this paper. The raw material, with approximately 40% kaolinite and 40% of 2:1 ...

Hollow cylinder simulation experiments of galleries in Boom Clay formation

Vincent Labiouse, Claire Sauthier, Shuang You

In the context of nuclear waste disposal in clay formations, laboratory experiments were performed to study at reduced scale the Excavation Damaged Zone (EDZ) induced by the construction of galleries in the Boom Clay formation. For this purpose, thick-wall ...

Consequences of the Thermal Transient on the Evolution of the Damaged Zone Around a Repository for Heat-Emitting High-Level Radioactive Waste in a Clay Formation: a Performance Assessment Perspective

Vincent Labiouse, Xing Li

A proper evaluation of the perturbations of the host rock induced by the excavation and the emplacement of exothermic wastes is essential for the assessment of the long-term safety of high-level radioactive waste disposals in clay formations. The impact of ...

Early warning thresholds for partially saturated slopes in volcanic ashes

Lyesse Laloui, Alessio Ferrari, John Eichenberger

Rainfall-induced landslides in steep soil slopes of volcanic origin are a major threat to human lives and infrastructure. In the context of constructing early warning systems in regions where extensive data on landslide occurrences and associated rainfall ...

Thermo-Hydro-Mechanical Modelling of Hollow Cylinder Laboratory Experiments on Boom Clay

Vincent Labiouse, Bertrand François

The aim of the TIMODAZ project is to investigate the effect of thermal changes on the excavation damaged zone (EDZ) around nuclear deep disposals in clay-based geological formations. In the framework of WP5.2 of this project, it is intended to develop cons ...

Three-phase medium model for filled rock joint and interaction with stress waves

Jian Zhao

A three-phase medium model is proposed in describing the dynamic property of filled rock joints and an analytical study on longitudinal wave transmission normally across a three-phase rock joint is presented. Parameters in the three-phase medium model were ...
