The CSH gel is an elusive material. Its variable composition and disordered nature
complicate a complete characterization of its atomic structure, and the elaboration of models …

Cement-based materials are widely utilized in infrastructure. The main product of hydrated
products of cement-based materials is calcium silicate hydrate (CSH) gels that are …

Water migration in the gel pore of the calcium silicate hydrate (CSH) influences the durability
of cement-based material. The water transport in nanoscale gel pore is dramatically different …

This paper investigates the effect of KOH and NaOH on CSH structure and solubility. Both
KOH and NaOH have a similar effect, they increase pH values and silicon concentrations …

This paper presents a review on the relationship between the composition, the structure and
the solution in which calcium silicate hydrate (C–S–H) is equilibrated. The silica chain length …

Synthesized calcium silicate hydrate (C–S–H) samples with Ca/Si ratios of 0.66, 1.0, and 1.5
have been exposed to atmospheric CO 2 at room temperature and high relative humidity …

C-(A)-SH (I) is a calcium silicate hydrate that is studied extensively as a model for the main
binding phase in concrete. It is a structurally imperfect form of 14 Å tobermorite that has …

For first time, an experimental and computational study has been conducted to define a
structural model for the CASH gel forming in alkali-activated slag (AAS) pastes that would …

The hydration and the microstructure of three alkali activated slags (AAS) with MgO contents
between 8 and 13 wt.% are investigated. The slags were hydrated in the presence of two …

Structural models for the primary strength and durability-giving reaction product in modern
cements, a calcium (alumino) silicate hydrate gel, have previously been based solely on non …
