Ubiquitous aluminium contamination in water and amyloid hybrid membranes as a sustainable possible solution

Francesco Stellacci, Malvina Julia Ida Pauchard, Raffaele Mezzenga

We develop a membrane technology based on amyloid fibrils to remove aluminium from water and minimize its exposure to humans. We study aluminium adsorption by amyloid fibrils by evaluating the binding isotherms, the thermodynamics and the effects of differ ...

Basic creep and autogenous shrinkage of Limestone Calcined Clay Cement (LC3)

Julien Ston

The use of supplementary cementitious materials (SCM) to lower the clinker factor of cements is now commonplace, for it benefits performance, economics and ecology. This thesis focuses on ternary blends of limestone and calcined kaolinitic clays, two very ...

Hydration Study of Limestone Calcined Clay Cement (LC3) Using Various Grades of Calcined Kaolinitic Clays

Karen Scrivener, François Henri Avet

In this study, the influence of the calcined kaolinite content of calcined clay on the hydration of Limestone Calcined Clay Cement (LC3-50) is investigated. It is shown that with the increase of the calcined kaolinite content of the calcined clay, the clin ...

Determining the Surface Structure of Silicated Alumina Catalysts via Isotopic Enrichment and Dynamic Nuclear Polarization Surface-Enhanced NMR Spectroscopy

David Lyndon Emsley, Brennan James Walder, Jasmine Viger-Gravel

Isotopic enrichment of Si-29 and DNP-enhanced NMR spectroscopy are combined to determine the detailed surface structure of a silicated alumina catalyst. The significant sensitivity enhancement provided by DNP is vital to the acquisition of multinuclear and ...

RECOVERY OF PRECIOUS METALS FROM INCINERATION BOTTOM ASH

Incineration bottom ash (IBA), the final solid residues from Energy of Waste Facilities (EfW), holds a huge potential for recovery of valuable metals and a complete reuse of the residual mineral matter. Modern treatment technologies allow for a recovery of ...

Investigation of the grade of calcined clays used as clinker substitute in Limestone Calcined Clay Cement (LC3)

François Henri Avet

The combination of calcined kaolinitic clays and limestone in Limestone Calcined Clay Cement (LC3) is a promising approach to reduce the cost and the CO2 emissions of cement production by reducing the clinker content of cement. This thesis investigates the ...

Approximation numérique des écoulements turbulents dans des cuves d'électrolyse de l'aluminium

Jonathan Rochat

Aluminium is a metal extracted from bauxite ore using electrolysis process in cells of big size. A huge electric current goes in the cell through an electrolytic bath and aluminium liquid. These currents generate strong magnetic forces that allow the bath ...

Rapid screening tests for supplementary cementitious materials: past and future

Karen Scrivener, Ruben Anton Snellings

Rapid screening tests for supplementary cementitious materials (SCMs) have been in use for over 150 years. Over the years a multitude of methods have been put forward to predict the strength development of SCMblended mortars and concrete. This paper summar ...

Atomistic Modeling of Processing Issues for Transparent Polycrystalline Alumina

Abhishek Tewari

Transparent polycrystalline alumina has many possible promising areas of application from jewelry and the watch industry to wave guides, energy economical lamp envelopes, and optical windows. Ultrahigh density, submicron sized grains and/or oriented micros ...

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 ...
