Characterisation and hydration kinetics of beta-C2S synthesised with K2SO4 as dopant

Karen Scrivener, Franco Alberto Zunino Sommariva, Shashank Bishnoi, Sreejith Krishnan

In this study, a protocol for synthesising beta-C2S using K2SO4 as a dopant has been reported. Quantitative X-Ray diffraction was used to characterise synthesised samples. It was observed that it is possible to synthesise beta-C2S with high purity (>96 wt% ...

Rapid, Robust, and Relevant (R3) Reactivity Test for Supplementary Cementitious Materials

Karen Scrivener, Ruben Anton Snellings, François Henri Avet, Xuerun Li

Although supplementary cementitious materials (SCMs) are now commonly accepted and widely used, consensus has not been reached for methods to test their chemical reactivity. A multitude of test methods exist but often fall short on one or more of the key f ...

Insights about the Absence of Rb Cation from the 3D Perovskite Lattice: Effect on the Structural, Morphological, and Photophysical Properties and Photovoltaic Performance

Michael Graetzel, Shaik Mohammed Zakeeruddin, Mohammad Ibrahim Dar, Gwénolé Jean Jacopin, Neha Arora, Ryusuke Uchida, Silvia Binet

Efficiencies >20% are obtained from the perovskite solar cells (PSCs) employing Cs+ and Rb+ based perovskite compositions; therefore, it is important to understand the effect of these inorganic cations specifically Rb+ on the properties of perovskite struc ...

Reactor Dynamics Investigation Based On Calorimetric Data

Thierry Meyer, Francis Stoessel, Michal Dabros, Charles Ibrahim Guinand

A simple and general procedure has been developed to determine the thermal behaviour of a reactor based on heat balance, PID temperature control, and jacket behaviour. Using only temperature heating/cooling ramps followed by isothermal stages, such a proce ...

Impact of water activity on the stability of ettringite

Karen Scrivener, Thomas Matschei

The stability of ettringite as function of temperature and water vapour pressure was studied on synthetic samples using X-ray diffraction, thermogravimetric analysis, sorption balance measurements and different calorimetry techniques. Crystalline ettringit ...

Gas separations in metal-organic frameworks

Wendy Lee Queen, Miguel Gonzalez

Owing to their high surface areas, tunable pore dimensions, and adjustable surface functionality, metal-org. frameworks (MOFs) can offer advantages for a variety of gas storage and gas sepn. applications. In an effort to help curb greenhouse gas emissions ...

Pozzolanic reactivity of low grade kaolinitic clays: Influence of calcination temperature and impact of calcination products on OPC hydration

Karen Scrivener, Adrian Alujas Diaz, Rodrigo Fernandez Lopez

The influence of thermal activation temperature in the pozzolanic reactivity of low grade kaolinitic clay and the impact of calcination products in OPC hydration are assessed in this paper. The raw material, with approximately 40% kaolinite and 40% of 2:1 ...

Understanding the Filler Effect on the Nucleation and Growth of C-S-H

Karen Scrivener, Elise Marie Jeanne Berodier

The filler effect, due to the physical presence of mineral additions in cement, is mainly known to accelerate the hydration of the clinker component. Previously, this was attributed to the surface of the filler providing nucleation sites for C-S-H as there ...

Impact of Annealing on the Early Hydration of Tricalcium Silicate

Karen Scrivener, Marco Cantoni, Amélie Bazzoni

It was recently proposed that the induction period observed during the hydration of tricalcium silicate could be explained by the build-up of ions in solution. Due to the importance of defects in this mechanism, this work describes the effect of different ...
