This work reviews state of the art representative volume element (RVE) generation
techniques for heterogeneous materials. To this end, we present a systematic classification …

Concrete is flying off, but it is simultaneously facing tremendous challenges in terms of
environmental impact, financial needs, societal acceptance and image. Based on an …

The interfacial transition zone (ITZ) has a major detrimental impact on the structural
performance of concrete. This negative impact can be modulated by introducing mineral …

Current demand for highly sustainable concrete, eg alkali-activated fly ash-slag (AAFS)
concrete, urges understanding the links between microstructure and micromechanical …

In this work, we conducted an experimental and micromechanical investigation on the
mechanical and chloride diffusion properties of recycled aggregates concrete (RAC). Due to …

Concrete is the largest volume material used by man and is irreplaceable for innumerable
large infrastructure developments. From the point of view of natural resources, ecology and …

Debates remain on the influencing factor and long-term performance of CSH-seeded paste.
In this study, phase-pure seeds were prepared from diluted Ca 3 SiO 5 hydration. The seed …

A hydration model for Portland cement pastes modified with nano-silica in partial substitution
is formulated based on the nucleation growth process from microstructural investigations …

Strength and other mechanical properties of cement and concrete rely upon the formation of
calcium–silicate–hydrates (C–S–H) during cement hydration. Controlling structure and …

This work addresses a knowledge gap in meso-scale modelling of concrete–the effect of
selected computational ITZ thickness on predicted macroscopic behaviour. A novel …
