Gluconate and hexitols effects on C-S-H solubility
Lina Bouzouaid, Barbara Lothenbach, Alejandro Fernandez-Martinez +1
This study investigates the effect of gluconate, a carboxylate ion, and three uncharged hexitols, D-sorbitol, D-mannitol and D-galactitol on the solubility of C-S-H. Thermodynamic…
Portlandite solubility and Ca2+ activity in presence of gluconate and hexitols
Lina Bouzouaid, Barbara Lothenbach, Alejandro Fernandez-Martinez +1
The current paper investigates the impact of gluconate, D-sorbitol, D-mannitol and D-galactitol on calcium speciation at high pH values by i) solubility measurements of portlandite…
Textural properties of synthetic nano-calcite produced by hydrothermal carbonation of calcium hydroxide
German Montes-Hernandez, Alejandro Fernandez-Martinez, L. Charlet +2
The hydrothermal carbonation of calcium hydroxide (Ca(OH)2) at high pressure of CO2 (initial PCO2 1/4 55 bar) and moderate to high temperature (30 and 90 1C) was used to synthesize…
Arsenite sorption and co-precipitation with calcite
Gabriela Roman-Ross, Gabriel Cuello, Xavier Turrillas +2
Sorption of As(III) by calcite was investigated as a function of As(III) concentration, time and pH. The sorption isotherm, i.e. the log As(III) vs. log [As(OH)3 degrees / Assat] p…
Structure of chalcogenide glasses by neutron diffraction
Gabriel Cuello, Andrea Piarristeguy, Alejandro Fernandez-Martinez +2
The purpose of this work is to study the change in the structure of the Ge-Se network upon doping with Ag. The total structure factor S(Q) for two samples has been measured by neut…
Arsenic uptake by gypsum and calcite: Modeling and probing by neutron and x-ray scattering
Alejandro Fernandez-Martinez, Gabriel J. Cuello, Gabriela Roman-Ross +4
Here we report on two structural studies performed on As-doped gypsum (CaSO4 2H2O) and calcite (CaCO3), using neutron (D20-ILL) and x-ray (ID11-ESRF) diffraction data and EXAFS (BM…
