Assessment of early age properties of cementitious system through isopropanol-water replacement in the mixing water

Karen Scrivener, Emmanuel Gallucci, Xiao Wang

In this study, a new method to assess early properties of cementitious materials by water-solvent replacement is investigated. Isopropanol was used to replace a part of mixing water of binder paste, limiting the maximum degree of hydration it can achieve. ...

En route to multi-model scheme for clinker comminution with chemical grinding aids

Mark Sawley, Emmanuel Gallucci, David Geissbühler

We present a multimodel simulation approach, targeted at understanding the behaviour of comminution and the effect of grinding aids in industrial cement mills. On the atomistic scale, we use molecular dynamics (MD) simulations with validated force field mo ...

Effect of temperature on the microstructure of calcium silicate hydrate (C-S-H)

Karen Scrivener, Emmanuel Gallucci, Xiuwei Zhang

Temperature affects the properties of concrete through its effect on the hydration of cement and its associated microstructural development. This paper focuses on the modifications to C-S-H induced by isothermal curing between 5 and 60 degrees C. The resul ...

Effect of mixing on the early hydration of alite and OPC systems

Patrick Juilland, Karen Scrivener, Emmanuel Gallucci, Aditya Kumar

The kinetics of hydration of cementitious materials is sensitive to the mixing procedure. High shear mixing conditions lead to an increase in the kinetics of hydration at early age compared to low shearing conditions such as hand mixing. In this study the ...

Topology of evolving pore networks

Emmanuel Gallucci, Marco Stampanoni

Morphological and topological quantification of complex pore networks is of great relevance for environmental engineering, earth science and industry. Recent developments of 3D imaging techniques such as X-ray microtomography or X-ray microscopy provide an ...

Methods for determination of degree of reaction of slag in blended cement pastes

Karen Scrivener, Emmanuel Gallucci, Vanessa Kocaba

To measure the degree of reaction of slag in blended pastes, five methods were studied. Selective dissolution and differential scanning calorimetry are shown to be unreliable, SEM-BSE-IA-mapping is time consuming, but does provide good results with a reaso ...

Physical and microstructural aspects of iron sulfide degradation in concrete

Karen Scrivener, Emmanuel Gallucci

The microstructural aspects of iron sulfide degradation in dam concrete were investigated by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) in both dam concrete samples and laboratory concrete. The results show that iron sulfid ...

Interaction between BaCO3 and OPC/BFS composite cements at 20 degrees C and 60 degrees C

Emmanuel Gallucci

A BaCO3 slurry, containing radioactive C-14, is produced during the reprocessing of spent nuclear fuel. This slurry is encapsulated in a Portland-blastfurnace slag composite cement. The effect of BaCO3 on the hydration of OPC and Portland-blastfurnace slag ...

Microstructural development of early age hydration shells around cement grains

Karen Scrivener, Prakash Chandra Mathur, Emmanuel Gallucci

An important microstructural aspect of the early hydration of Portland cement (K) is the formation of a shell of hydration products around cement grains. There is, at present, limited information on the mechanism of formation of the shell and of the chemis ...

Influence of self heating and Li2SO4 addition on the microstructural development of calcium aluminate cement

Karen Scrivener, Emmanuel Gallucci, Christophe Gosselin

Hydrated Calcium Aluminate Cement (CAC) is known to have a complex microstructure involving different phase assemblages strongly dependant on the temperature. This work presents an experimental approach to study the microstructure of CAC pastes from the fi ...

Quantitative microstructural characterisation of cement paste submitted to different moderate temperature and loading conditions

Karen Scrivener, Emmanuel Gallucci

The temperature is known to influence the strength and durability of concrete. Temperature has also a great influence on the creep of cementitious materials. Previous investigations have not provided a complete understanding of these effects; in particular ...

Durability Of Field Concrete Made Of Portland Cement And Supplementary Cementitious Materials Under Several European Exposure Conditions

Karen Scrivener, Emmanuel Gallucci, Aude Chabrelie

Deterioration of cementitious materials by sulfate ions is a concern for concrete in contact with ground water (and in a lesser extent sea water) in many parts of Europe, and is an important issue for underground construction identified as a major area for ...
