Advances in hydration and thermodynamics of cementitious systems

Karen Scrivener, Patrick Juilland, Aslam Kunhi Mohamed, Fabien Jacques Michel Georget, Thomas Matschei

Optimising the hydration of cementitious materials is crucial to leverage their full potential and avoid wasting resources, embodied energy and CO2. Understanding the fundamental mechanisms is key to reach these objectives. In this paper, we review progres ...

Advances in understanding cement hydration mechanisms

Karen Scrivener, Patrick Juilland, Aslam Kunhi Mohamed, Alexandre Reda Constantin William Caleb Ouzia

Progress in understanding hydration mechanisms of alite and Portland cement is reviewed. Up to the end of the induction period, dissolution rates determined by the undersaturation of the solution dominate the reaction, but, better understanding is needed a ...

Advances in understanding hydration of Portland cement

Karen Scrivener, Patrick Juilland

Progress in understanding hydration is summarized. Evidence supports the geochemistry dissolution theory as an explanation for the induction period, in preference to the inhibiting layer theory. The growth of C-S-H is the principal factor controlling the m ...

Effect of mixing on the early hydration of alite and OPC systems

Karen Scrivener, Emmanuel Gallucci, Aditya Kumar, Patrick Juilland

The kinetics of hydration of cementitious materials is sensitive to the mixing procedure. High shear mixing conditions lead to an increase in the kinetics of hydration at early age compared to low shearing conditions such as hand mixing. In this study the ...

The origin of early age expansions induced in cementitious materials containing shrinkage reducing admixtures

Karen Scrivener, Barbara Lothenbach, Patrick Juilland

Studies on the early-age shrinkage behavior of cement pastes, mortars, and concretes containing shrinkage reducing admixtures (SRAs) have indicated these mixtures frequently exhibit an expansion shortly after setting. While the magnitude of the expansion h ...

Early hydration of cementitious systems

Patrick Juilland

Underground job sites such as tunnels and mines rely on the quality of recently sprayed concrete to secure freshly excavated zones. Rapid setting and early high strength development are required for safety as well as for the rapid progression of the constr ...
