Caries Detection with Near-Infrared Transillumination Using Deep Learning

Henry Markram, Felix Schürmann, Taylor Howard Newton, Francesco Casalegno

Dental caries is the most prevalent chronic condition worldwide. Early detection can significantly improve treatment outcomes and reduce the need for invasive procedures. Recently, near-infrared transillumination (TI) imaging has been shown to be effective ...

Kinetics of mixing-water repartition in UHPFRC paste and its effect on hydration and microstructural development

Eugen Brühwiler, Karen Scrivener, Emmanuel Denarié, Arnaud Charles Albert Muller, Mohammadhadi Kazemi Kamyab

The hydration of an ultra-high performance fibre reinforced concrete (UHPFRC) paste with a water to cement ratio of 0.18 was followed by proton nuclear magnetic resonance (1H NMR) alongside more classical techniques for hydration kinetics, and microstructu ...

Water Redistribution-Microdiffusion in Cement Paste under Mechanical Loading Evidenced by H-1 NMR

Karen Scrivener, Pietro Lura

The mobility of water within the microstructure of hardened cement paste has been at the center of a long-lasting debate, motivated by the need to understand the fundamental mechanisms that play a role in drying, shrinkage, creep, and thermal expansion. Ou ...

Prediction of autogenous shrinkage of cement pastes as poro-visco-elastic deformation

Karen Scrivener, Zhangli Hu, Pietro Lura

Precise and robust predictions of autogenous shrinkage of high performance concrete are essential to limit self-induced stresses and cracking in modern concrete structures. This paper presents predictions of autogenous shrinkage for three cement pastes of ...

Modeling the kinetics of the main peak and later age of alite hydration

Alexandre Reda Constantin William Caleb Ouzia

The aim of this thesis is to understand the mechanisms underlying the main hydration peak and later ages of alite hydration; it proposes new mechanistic models for these two stages. Alite is the main constituent of Portland Cement (PC), and is responsible ...

Concrete Performance of Limestone Calcined Clay Cement (LC3) Compared with Conventional Cements

Karen Scrivener, Lionel Sofia, François Henri Avet

This study aims to demonstrate the robustness of concrete made of limestone calcined clay cement (LC3). Two campaigns were carried out using 375 kg.m(-3) and 500 kg.m(-3) of binder and targeting plastic and self-placing workability, respectively. The concr ...

Chemical shrinkage of ye'elimite with and without gypsum addition

Karen Scrivener, Mohsen Ben Haha, Frank Bullerjahn

Ye'elimite (Ca4Al6O12SO4 or C(4)A(3)S) is the main hydraulic mineral present in calcium sulphoaluminate cement (CSA). Its reaction is responsible for the (early) hydration and associated cement properties such as the chemical shrinkage. This paper discusse ...

Review of fundamental assumptions of the Two-Phase model for aggregate interlocking in cracked concrete using numerical methods and experimental evidence

Aurelio Muttoni, Guillaume Anciaux, Miguel Fernández Ruiz, Mohit Pundir, Max Tirassa

Aggregate interlocking allows transferring shear and normal stresses through open cracks, and is considered to significantly contribute to the force transfer in cracked concrete. The complex phenomenon depends on the roughness of cracked surfaces, where ma ...

Impact of sodium gluconate on white cement-slag systems with Na2SO4

Karen Scrivener, Berta Mota Gassó, Thomas Matschei

Sodium gluconate has been shown to compensate the impact of alkalis on the long term strength development of cement pastes. This work studies the impact of sodium gluconate combined with Na2SO4 on the microstructural development of white cement-slag system ...

Intrinsic viscoelasticity of C-S-H assessed from basic creep of cement pastes

Karen Scrivener, Julien Ston, Zhangli Hu, Adrien Jean Régis Maurice Hilaire, Pietro Lura

This paper investigates the fundamental mechanisms behind the effect of supplementary cementitious materials (SCMs) on the basic creep behavior of cement pastes. The intrinsic creep properties of the C-S-H gel are assessed based on measurements of uniaxial ...
