Visco-elastic behavior of blended cement pastes at early ages

Karen Scrivener, Zhangli Hu, Adrien Jean Régis Maurice Hilaire, Pietro Lura

This study aims at elucidating the visco-elastic behavior of hardening blended cement pastes, focusing on uni-axial basic compressive creep tests at early loading ages. Cement pastes with Portland cement only or blended with quartz or fly ash (both at a su ...

Effect of a novel starch-based temperature rise inhibitor on cement hydration and microstructure development

Karen Scrivener, Alexandre Reda Constantin William Caleb Ouzia, Cheng Yu

This study investigates the mechanism by which a novel starch-based admixture named Temperature Rise Inhibitor (TRI) modifying cement hydration and limiting heat evolution. This admixture is designed to avoid thermal cracking of concrete. Depending on the ...

Microstructural modelling of autogenous shrinkage in Portland cement paste at early age

Shashank Bishnoi

Purpose This paper aims to develop a numerical, micromechanical model to predict the evolution of autogenous shrinkage of hydrating cement paste at early age (up to 7 days). Autogeneous shrinkage can be important in high-performance concrete characterized ...

Young's modulus and creep of calcium-silicate-hydrate compacts measured by microindentation

Karen Scrivener, Zhangli Hu, Pietro Lura

In this paper, compacts of synthetic calcium silicate hydrate (C-S-H) with 0.8-1.5 calcium-to-silicon ratio (Ca/Si) and 30-80% porosity were prepared by one-direction cold pressing. The Young's modulus and the creep of C-S-H compacts were measured by micro ...

Unravelling chloride transport/microstructure relationships for blended-cement pastes with the mini-migration method

Karen Scrivener, Fabien Jacques Michel Georget, William Wilson

A chloride mini-migration method is proposed to estimate effective diffusion coefficients at the scale of the cement paste and to investigate mechanisms with complementary microstructure analyses on the same material. Blended-cement pastes with a wide rang ...

Effect of sulfate on C-S-H at early age

Karen Scrivener, Arnaud Charles Albert Muller

The effect of increasing sulfate contents on the hydration of white cement was studied with a multi-technique approach. Quantitative X-Ray Diffraction (XRD) revealed that adding more gypsum in the cement resulted in more ettringite formation. Combining iso ...

The Influence of some calcined clays from Nigeria as clinker substitute in cementitious systems

Karen Scrivener, François Henri Avet, Akindehinde Ayotunde Akindahunsi

This paper examines the possibility of the use of some clays calcined from Nigeria as partial substitutes for clinker in the production of Limestone Calcined Clay Cement (LC3). The clays were calcined in the oven at a temperature of 800 degrees C and for o ...

The effect of sodium hydroxide on Al uptake by calcium silicate hydrates (C S H)

Christian Ludwig, Barbara Lothenbach, Sonya Barzgar, Mohamed Tarik, Alessio Di Giacomo

To reduce the CO2 emissions from cement production, Portland cement (PC) is partially replaced by supplementary cementitious materials (SCM). Reactions of SCM with PC during hydration leads to the formation of CSH with more silicon and aluminum than in PC, ...
