Factors affecting the reactivity of slag at early and late ages

Karen Scrivener, Yosra Briki, Mohsen Ben Haha

This study investigates the difference between the reactivity of slag in NaOH solution (w/s = 100) and in cement paste (w/b = 0.4). The reactivity of slag is much higher in NaOH solution than in cement paste. When the NaOH solution is saturated with portla ...

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 ...

Basic creep of cement paste at early age - the role of cement hydration

Karen Scrivener, Pietro Lura

In this work, the uniaxial creep in compression during the first days of hydration is studied experimentally on cement pastes with w/c of 0.50. to order to assess the effect of the evolving microstructure on creep, the so-called equivalent systems are empl ...

Quantification of amorphous siliceous fly ash in hydrated blended cement pastes by X-ray powder diffraction

Karen Scrivener, Ruben Anton Snellings, Xuerun Li

X-ray powder diffraction (XRPD)-based quantitative phase analysis is a common technique for studying the hydration of cementitious systems. Hydrated cements often comprise several amorphous or nanocrystalline phases. This paper presents a protocol for the ...

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 ...

Effect of cement substitution by limestone on the hydration and microstructural development of ultra-high performance concrete (UHPC)

Karen Scrivener, Wei Sun, Wei Huang

The effect of limestone on the hydration and microstructural development of ultra high performance concrete (UHPC) with different levels of replacement (34%, 54% and 74% by volume) was investigated. Up to 54% replacement of cement by limestone the mixes sh ...

The pore solution of blended cements: a review

Barbara Lothenbach, Ruben Anton Snellings

This paper is the work of working group 3 of the RILEM Technical Committee on Hydration and Microstructure of Concrete with SCM (TC 238-SCM). The pore solution is an essential but often overlooked part of hydrated cements. The composition of the cement por ...

Atomistic Simulations of Silicate Species Interaction with Portlandite Surfaces

Paul Bowen, Sandra Caroline Galmarini, Aslam Kunhi Mohamed

Portlandite (Ca(OH)(2), CH) is the second most abundant hydrate formed in the reaction of Portland cement with water, making it an important component in the built environment. Formation of CH is closely linked to the growth of the main hydrate phase, calc ...
