Query: Gluconate and hexitols effects on C-S-H solubility   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 modeling was used to determine the kind and amount of
Ca-organic-silicate-OH complexes that potentially form in the conditions
studied. All the organics form complexes with calcium and hydroxide, In
addition, heteropolynuclear organics complexes with calcium, hydroxide and
silicate are observed at high pH values and high calcium concentrations with
the exception of mannitol. The strength of complexation with silicate decreases
from gluconate > sorbitol > galactitol. The adsorption of the selected organics
on portlandite and C-S-H systems follows the order gluconate >> sorbitol >
mannitol = galactitol. For C-S-H system buffered with Ca(OH)2, a typical
Langmuir isotherm was found and adsorption on C-S-H increased with the Ca/Si
ratio as well as with the increase of the organic concentration.
