Nanoindentation Size Effects for Calcium Silicate Hydrate

, 2010
Hardness of Calcium Silicate Hydrate (CSH) at different ages was measured by nanoindentation test. The results show obvious indentation size effect in hardness of CSH. Hardness decreases with increasing depth.

The Atomic-Level Structure of Cementitious Calcium Aluminate Silicate Hydrate Determined by NMR [PDF]

, 2021
We review our recent paper which resolves the long-standing dilemma of the location and nature of the six-fold coordinated aluminum in calcium aluminate silicate hydrate (C-A-S-H) samples.

Machine Learning Potential for Calcium Silicate Hydrates With Broad Compositional and Structural Diversity

Advanced Science, EarlyView.
Existing machine learning potentials remain limited in their ability to generalize across the broad chemical and structural variability of C–S–H. Here, a representative DFT‐labeled dataset is constructed through large‐scale model generation, redundancy‐controlled screening, first‐principles optimization, and targeted sampling of non‐equilibrium ...

Overcoming Out‐of‐Plane Conduction by Changing Nanosheet Morphology

Advanced Science, EarlyView.
HTaWO6 membrane made of stacked nanotubes exhibits high out‐of‐plane proton conductivity of 1.7 mS/cm. High current density (1.26 A cm−2) and power density (294 mW cm−2) indicate the potential as a fuel‐cell electrolyte. The morphology‐driven strategy establishes topology engineering as a new design principle for efficient ion transport in two ...

2D Vermiculite Nanosheets Encapsulated in Hydrogel Electrolyte for Shuttle‐Free and Dendrite‐Inhibited Zinc‐Iodine Batteries

Advanced Science, EarlyView.
A dual‐network hydrogel was prepared via a one‐pot method, incorporating vermiculite nanosheets as an additive. The negatively charged vermiculite nanosheets not only coordinate with zinc ions to facilitate Zn plating/stripping and suppress Zn dendrite growth, but also adsorb polyiodides to inhibit the shuttle effect, which significantly improves the ...

Microstructure of calcium silicate hydrates

Cement and Concrete Research, 1971
WHILE CONSIDERABLE ATTENTION AND STUDY HAVE BEEN DEVOTED TO THE STRUCTURE AND MORPHOLOGY OF CALCUM SILICATE HYDRATE, NEITHER THE INTERRELATION BETWEEN THE VARIOUS OBSERVED PARTICLE SHAPES NOR THEIR ROLE IN FORMATION OF THE FINAL MICROSTRUCTURE OF THE HARDENED PASTE HAS BEEN ESTABLISHED.
