متن کاملSolubility 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 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...

متن کاملSynthesis of zeolite membranes on calcium silicate support and their bioactive response
The synthesis of calcium silicate supported zeolite membrane was carried out by second growth method. The chemical nature of the functionalizing agent on the formation of homogenous zeolite membrane was evaluated. One monomer and two cationic polymers were used: 3-aminopropyltriethoxysilane (APS), polyethylenimine (PEI) and polydiallyldimethylammonium chloride (PDDA). The support was subjected ...
