Factors influencing the hydration kinetics of ye'elimite; effect of mayenite

Karen Scrivener, Mohsen Ben Haha, Frank Bullerjahn

The aim of this study was to understand the origin of the variation in the hydraulic reactivity of ye'elimite systems. To this end, the hydration of two clinkers, one composed mainly of synthetic stoichiometric (C(4)A(3)(S) over bar) "Y" and the other of a ...

Hydration reactions and stages of clinker composed mainly of stoichiometric ye'elimite

Karen Scrivener, Emmanuelle Boehm Courjault, Mohsen Ben Haha, Frank Bullerjahn

Ye'climitc (Ca4Al6O12SO4 or C(4)A(3)(S) over bar) is the main hydraulic mineral present in calcium sulfoaluminate cement (CSA). The hydration of ye'elimite is responsible for the early age cement properties. We identify 5 stages in the hydration of neat st ...

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

Karen Scrivener, Cyrille Dunant, Mohsen Ben Haha, 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 ...

Reactivity tests for supplementary cementitious materials: RILEM TC 267-TRM phase 1

Karen Scrivener, Mathieu Antoni, Ruben Anton Snellings, Mohsen Ben Haha, Shashank Bishnoi, Xuerun Li, Anuj Parashar, Yuvaraj Dhandapani

A primary aim of RILEM TC 267-TRM: Tests for Reactivity of Supplementary Cementitious Materials (SCMs) is to compare and evaluate the performance of conventional and novel SCM reactivity test methods across a wide range of SCMs. To this purpose, a round ro ...

Influence of calcium and magnesium carbonates on hydration kinetics, hydrate assemblage and microstructural development of metakaolin containing composite cements

Mohsen Ben Haha, Pawel Tadeusz Durdzinski

The hydration of metakaolin composite cements containing quartz, natural limestone and dolomite rock is studied using a multi-method approach and modelling. The study demonstrates that the calcite present in limestone and dolomite rock is very reactive. Co ...

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

Karen Scrivener, Barbara Lothenbach, Mohsen Ben Haha, 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

Karen Scrivener, Mohsen Ben Haha, 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 ...

Development of a new rapid, relevant and reliable (R-3) test method to evaluate the pozzolanic reactivity of calcined kaolinitic clays

Karen Scrivener, Ruben Anton Snellings, Mohsen Ben Haha, François Henri Avet, Adrian Alujas Diaz

The present paper introduces a new rapid, relevant and reliable (R-3) test to predict the pozzolanic activity of calcined clays with kaolinite contents ranging from 0 to 95%. The test is based on the correlation between the chemical reactivity of calcined ...

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

Karen Scrivener, Cyrille Dunant, Mohsen Ben Haha, 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

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 ...
