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 …

Nanoporous media consist of homogeneous or heterogeneous porous material in which a
significant part of the pore size distribution lies in the nanometer range. Clayey rocks …

Despite its ubiquitous presence in the built environment, concrete's molecular-level
properties are only recently being explored using experimental and simulation studies …

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 …

A new thermodynamic model, CASH+, is proposed, aimed at accurately describing
equilibrium composition, stability, solubility, and density of CSH gel-like phases at varying …

Two magnesium silicate hydrates (MSH) with structural magnesium/silicon ratios of
0.57±0.08 and 1.07±0.13 were synthesized at room temperature, with one year of synthesis …

X-ray diffraction (XRD) patterns were calculated and compared to literature data with the aim
of investigating the crystal structure of nanocrystalline calcium silicate hydrates (CSH), the …

Calcium silicate hydrate (CSH) and magnesium silicate hydrate (MSH) have been described
as two separate phases. This work investigates their stability domains and the possible …

Calcium silicate hydrate (CSH) is made by mixing calcium hydroxide (portlandite), silica and
water at two calcium oxide to silica (C/S) ratios, using nano-silica and silica fume. We …

We present new results on solid (monolithic) synthetic CSH made at room temperature from
easily obtainable calcium sources (calcium oxide, calcium hydroxide) and nanosilica (w/s …
