Solubility and Structure of Calcium Silicate Hydrate
A poorly crystalline class of calcium silicate hydrates known as CSH possesses extensive disorder and structural variations at the nanometer scale. The extent of these variations has generally obscured a comprehensive understanding of the CSH nanostructure, but new relationships between solubility and structure appear to shed new light on this old problem. These relationships were inspired ...
متن کاملA New Biphasic Dicalcium Silicate Bone Cement Implant
This study aimed to investigate the processing parameters and biocompatibility of a novel biphasic dicalcium silicate (C₂S) cement. Biphasic α´L + β-C₂Sss was synthesized by solid-state processing, and was used as a raw material to prepare the cement. In vitro bioactivity and biocompatibility studies were assessed by soaking the cement samples in simulated body fluid (SBF) and human adipose ste...
متن کاملAb-initio Molecular Dynamics Study on Crystal Structure of Beta-dicalcium Silicate
The crystal structures and hydraulic activities of β and γform dicalcium silicates (β-C2S, γ-C2S) were analyzed by ab-initio calculation based on quantum mechanics. The mean distances less than 4 Å to the neighboring Ca atoms for all of independent Ca atoms were calculated within unit cell. Ca-Ca mean distances are 3.56 Å in β-C2S and 3.75 Å in γ-C2S. The shortening of Ca-Ca distance causes ins...
متن کاملMechanism of stabilization of dicalcium silicate solid solution with aluminium.
Stoichiometric dicalcium silicate, Ca2SiO4, displays a well-known polymorphism with temperature. When this phase is doped by a range of elements, belite, one of the main phases of cements, is generated. Here, we thoroughly study the aluminum doping of dicalcium silicate. This type of study is important for cement characterization and also from a basic point of view. Ca2Si(1-2x)Al(2x)O(4-x)□(x) ...
متن کاملOrder and disorder in calcium-silicate-hydrate.
Despite advances in the characterization and modeling of cement hydrates, the atomic order in Calcium-Silicate-Hydrate (C-S-H), the binding phase of cement, remains an open question. Indeed, in contrast to the former crystalline model, recent molecular models suggest that the nanoscale structure of C-S-H is amorphous. To elucidate this issue, we analyzed the structure of a realistic simulated m...
