Multiscale understanding of tricalcium silicate hydration reactions [PDF]

, 2017
Tricalcium silicate, the main constituent of Portland cement, hydrates to produce crystalline calcium hydroxide and calcium-silicate-hydrates (C-S-H) nanocrystalline gel. This hydration reaction is poorly understood at the nanoscale.

Calcium silicate-based root canal sealers: a literature review

Restorative Dentistry & Endodontics, 2020
Epoxy resin-based sealers are currently widely used, and several studies have considered AH Plus to be the gold-standard sealer. However, it still has limitations, including possible mutagenicity, cytotoxicity, inflammatory response, and hydrophobicity ...

Structural models of random packing of spheres extended to bricks: Simulation of the nanoporous calcium silicate hydrates [PDF]

, 2009
Structure simulation algorithms of random packing of spheres and bricks have been developed. These algorithms were used to reproduce the nanostructure of the cementitious calcium silicate hydrates. The textural parameters (specific surface area, porosity,

Synchrotron Radiation Pair Distribution Function Analysis of Gels in Cements [PDF]

, 2017
The analysis of atomic ordering in a nanocrystalline phase with small particle sizes, below 5 nm, is intrinsically complicated because of the lack of long-range order.
