On shrinkage and structure changes of pure and blended Portland concretes

Yao Zhang, Catherine A. Davy, Grégory Tricot, Cyrille Albert-Mercier, Natacha Henry, Pieter Bertier, Fréderic Cazaux, Denis Damidot, Xavier Bourbon

This research investigates the long-term shrinkage and Relative Mass Loss (RML) of mature Portland concretes (pure CEMI and blended CEMV/A), at temperatures of 20°C and 80°C. When placed at 80°C and at relative humidities (RH) below 50-60%, concrete shrinkage increases with very slow stabilization…

Linearization of algebraic structures with operads and polynomial functors : Quadratic equivalences and the Baker-Campbell-Hausdorff formula for 2-step nilpotent varieties, Linéarisation de structures algébriques à l'aide d'opérades et de foncteurs polynomiaux : Les équivalences quadratiques et la formule de Baker-Campbell-Hausdorff pour les variétés 2-nilpotentes

Thibault Defourneau

The aim of this work consists of establishing the foundations and first steps of a research project which aims at a new understanding and generalization of the classical Baker-Campbell-Hausdorff formula with a conceptual approach, and its main application in group theory: refining a result of Mal…, Le travail de thèse contribue à établir des liens entre structures algébriques non-linéaires, décrites par des théories algébriques, et des structures algébriques linéaires, encodées par des algèbres sur une opérade linéaire. Pour les théories algébriques dont les modèles forment une catégorie semi…

Optimization of PZT ceramic IDT sensors for health monitoring of structures

Rafatou Takpara, Marc Duquennoy, Mohammadi Ouaftouh, Christian Courtois, Frédéric Jenot, Mohamed Rguiti

Surface acoustic waves (SAW) are particularly suited to effectively monitoring and characterizing structural surfaces (condition of the surface, coating, thin layer, micro-cracks…) as their energy is localized on the surface, within approximately one wavelength. Conventionally, in non-destructive…

Caractérisation mécanique de céramiques poreuses sous forme massive et de revêtement par indentation instrumentée Knoop, Mechanical characterization of porous bulk and coating ceramics by Knoop instrumented indentation

Ghailen Ben Ghorbal

L’indentation instrumentée est largement utilisée pour la détermination des propriétés mécaniques des matériaux, principalement la dureté et le module d’élasticité. Pour obtenir des données fiables, plusieurs corrections comme la prise en compte du défaut de pointe et la complaisance de l’…, Instrumented indentation is widely used for the assessment of mechanical properties, mainly hardness and elastic modulus. In order to obtain reliable results, analysis methodology has to refer several corrections, such as tip defect and frame compliance. However, these corrections are insufficient…

Molecular Chemistry and Engineering of Boron-Modified Polyorganosilazanes as New Processable and Functional SiBCN Precursors

Antoine Viard, Diane Fonblanc, Marion Schmidt, Abhijeet Lale, Chrystelle Salameh, Anne Soleilhavoup, Mélanie Wynn, Philippe Champagne, Sophie Cerneaux, Florence Babonneau, Georges Chollon, Fabrice Rossignol, Christel Gervais, Samuel Bernard

A series of boron-modified polyorganosilazanes was synthesized from a poly(vinylmethyl-co-methyl)silazane and controlled amounts of borane dimethyl sulfide. The role of the chemistry behind their synthesis has been studied in detail by using solid-state NMR spectroscopy, FTIR spectroscopy, and…
