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, David Geissbühler, Emmanuel Gallucci

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, Xiuwei Zhang, Emmanuel Gallucci

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

Karen Scrivener, Emmanuel Gallucci, Aditya Kumar, Patrick Juilland

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 ...
