Modelling Hydration Kinetics of Cementitous Systems

Aditya Kumar

The modeling platform µic has been extended to study the hydration of cement based systems. It is shown that the hydration kinetics of alite can be described through the implementation of two mechanisms: a solution controlled dissolution (SCD) mechanism fo ...

From Particles to Pillars

Josias Basil Wacker

Metal oxide nanoparticles and their applications (e.g. in nano-electronics, nano-optics or drug delivery) have seen a growing interest in the past decades. Traditional procedures to synthesize, functionalize and integrate nanoparticles in devices mostly ha ...

Changes in portlandite morphology with solvent composition: Atomistic simulations and experiment

Paul Bowen, Sandra Caroline Galmarini, Nicolas Ruffray

Experimental work has been done to determine changes in the particle shape of portlandite grown in the presence of different ions. To quantify the experimentally observed changes in morphology a new analysis tool was developed, allowing the calculation of ...

Mechanisms of cement hydration

Karen Scrivener

The current state of knowledge of cement hydration mechanisms is reviewed, including the origin of the period of slow reaction in alite and cement, the nature of the acceleration period, the role of calcium sulfate in modifying the reaction rate of tricalc ...

Template-free self-assembly of hierarchical ZnO structures from nanoscale building blocks

Klaus Kern, Kannan Balasubramanian, Vivek Pachauri

We study chemical bath deposition method for synthesizing large variety constructions of ZnO nanostructures. By varying reaction kinetics we control the shape, size and morphology to yield flower-like, rolling-pin-like, viscous-fingers-like and antenna-lik ...

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 ...
