Characterization of Fly Ashes by a Novel Method in the Scanning Electron Microscope

Cyrille Dunant, Mohsen Ben Haha, Karen Scrivener, Pawel Tadeusz Durdzinski

In this paper, we show a new technique to characterize fly ashes using scanning electron microscopy (SEM). Chemical composition of millions of points is measured by SEM-energy dispersive X-ray spectroscopy and plotted in a ternary frequency plot. This new ...

Outcomes of the RILEM round robin on degree of reaction of slag and fly ash in blended cements

Mohsen Ben Haha, Karen Scrivener, Barbara Lothenbach, Pawel Tadeusz Durdzinski

Working group 2 of the RILEM TC 238-SCM undertook a comparison of laboratories and techniques for the quantification of the degree of reaction of supplementary cementitious materials in blended cements. A common set of binary pastes of Portland cement with ...

Phase assemblage of composite cements

Mohsen Ben Haha, Karen Scrivener, Pawel Tadeusz Durdzinski

The phase assemblage of binary Portland cements with 45 wt% replacement by calcareous fly ash and slag has been investigated by experiment, mass balance and thermodynamic simulations. The input for these calculations was based on clinker reaction measured ...

Properties and pozzolanic reactivity of flash calcined dredging sediments

Pawel Tadeusz Durdzinski, Ruben Anton Snellings

Dredging of ports, harbours and waterways generates vast amounts of sediments that find few applications and need to be disposed of. In the port of Antwerp, Belgium, each year 450,000 t (dry matter) of dredging sediments are mechanically dewatered and stoc ...

Hydration of multi-component cements containing cement clinker, slag, calcareous fly ash and limestone

Pawel Tadeusz Durdzinski

Calcareous fly ashes are high-potential reactive supplementary cementitious materials, which present an interesting alternative to slowly reacting siliceous fly ashes and to slags, which availability is more and more limited. Themain factor against an accu ...

A new quantification method based on SEM-EDS to assess fly ash composition and study the reaction of its individual components in hydrating cement paste

Cyrille Dunant, Mohsen Ben Haha, Karen Scrivener, Pawel Tadeusz Durdzinski

Calcareous fly ashes are high-potential reactive residues for blended cements, but their qualification and use in concrete are hindered by heterogeneity and variability. Current characterization often fails to identify the dominant, most reactive, amorphou ...

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

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

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 ...
