Fly ash as an assemblage of model Ca-Mg-Na-aluminosilicate glasses

Karen Scrivener, Ruben Anton Snellings, Cyrille Dunant, Mohsen Ben Haha, Pawel Tadeusz Durdzinski

Model Ca-Mg-Na-aluminosilicate glasses based on compositions found in a calcareous fly ash were synthesised and their reactivity assessed in NaOH solution and in Portland cement paste. It was found that the reactivity followed the same trend in both system ...

Effect of accelerated carbonation on AOD stainless steel slag for its valorisation as a CO2-sequestering construction material

Muhammad Salman, Ruben Anton Snellings

Non-stabilized Argon Oxygen Decarburisation (AODNS) slag in powdered form was examined for its carbon dioxide sequestration capacity and for its potential utilisation in the fabrication of high value building materials. The curing of the sample was carried ...

The Effect of Mg on Slag Reactivity in Blended Cements

Karen Scrivener, Ruben Anton Snellings

Blast-furnace slags are widely used as supplementary cementitious materials in blended cements because of their relatively high reactivity. This study describes the effect of substituting Ca by Mg on the reactivity of synthetic glass with similar compositi ...

A toolbox of oligopeptide-modified polymers for tailored elastomers

Véronique Michaud, Holger Frauenrath, Emmanuel Croisier, Joël Cugnoni, Su Liang, Marijana Mionic Ebersold, Ruben Anton Snellings, Thomas Schweizer

Biomaterials are constructed from limited sets of building blocks but exhibit extraordinary and versatile properties, because hierarchical structure formation lets them employ identical supramolecular motifs for different purposes. Here we exert a similar ...

The existence of amorphous phase in Portland cements: Physical factors affecting Rietveld quantitative phase analysis

Karen Scrivener, Amélie Bazzoni, Ruben Anton Snellings

Rietveld quantitative phase analysis has become a widespread tool for the characterization of Portland cement, both for research and production control purposes. One of the major remaining points of debate is whether Portland cements contain amorphous cont ...

Use of X-ray diffraction to quantify amorphous supplementary cementitious materials in anhydrous and hydrated blended cements

Karen Scrivener, Ruben Anton Snellings

The content of individual amorphous supplementary cementitious materials (SCMs) in anhydrous and hydrated blended cements was quantified by the PONKCS [1] X-ray diffraction (XRD) method. The analytical precision and accuracy of the method were assessed thr ...

Solution-Controlled Dissolution of Supplementary Cementitious Material Glasses at pH 13: The Effect of Solution Composition on Glass Dissolution Rates

Ruben Anton Snellings

Supplementary cementitious materials (SCMs) are widely used to partially replace portland clinker in blended cements. Reducing clinker contents further without compromising the development of early strength necessitates a better assessment and enhancement ...

Lessons from a lost technology: The secrets of Roman concrete

Ruben Anton Snellings

Roman concrete was used as building material during Roman Imperial times for a great number of famous constructions with different functions. Well-known examples are aqueducts, for example the Pont du Gard in France and the Aqua Alexandrina in Rome, and nu ...
