Calcium-silicate-hydrate (C-S-H) is the major binding phase responsible for strength and durability of cementitious materials. The cohesive properties of C-S-H are directly related to the intermolecular forces between its layers at the nanoscale. Here, we employ free energy perturbation theory (FEP) to calculate intermolecular forces between crystalline C-S-H layers solvated in aqueous medium a...

Background Recently a new generation of endodontic sealers has been developed based on calcium silicate as MTA Fillapex, Endoseal MTA, Total Fill BC Sealer, EndoSequence BC Sealer, iRoot SP, Endo CPM sealer, MTA-Angelus and ProRoot Endo Sealer. A review of literature was conducted to discuss the composition, physicochemical properties, and clinical perspectives of calcium silicate based sealers...

Hydration of tri-calcium silicate (C3S) and di-calcium silicate (C2S) precipitates calcium-silicate-hydrate (CSH) which is the bonding phase responsible for the strength of cementitious materials. Substitution of part of C3S and C2S with aluminumcontaining additives alters the chemical composition of hydration products by precipitating calcium-aluminate-silicatehydrate (CASH). Incorporation of ...

The C-S-H gel is an elusive material. Its variable composition and disordered nature complicate a complete characterization of its atomic structure, the elaboration models key to understanding it. This work aims review those proposed models, dividing them into empirical computational models. After brief description related crystalline calcium silicate hydrates, based on interpretation experimen...

In the current study, development of silicate structure synthetic calcium hydrates with different contents was followed by in-situ infrared (IR) spectroscopy and correlated to phase evaluated X-ray diffraction (XRD). A baseline correction method initially developed for diffractograms successfully adapted complex background fingerprint region in IR, which significantly contributed signal quality...
