dc.description.abstract | The uptake of chloride (Cl - ) and isosaccharinic acid (ISA, main degradation product of cellulose) by cement paste with high slag content (CEM III/C) was investigated with batch sorption experiments with 36 Cl and inactive ISA. A weak uptake of chloride was quantified (0.43 <= R d [L center dot kg - 1 ] <= 5.8), consistently with previous observations for Portland cement. C -S -H, AFm and hydrotalcite are suggested as primary sinks for Cl - . XRD confirmed the formation of Friedel's salt at [NaCl] >= 1 M, consistent with thermodynamic calculations. ISA exhibited moderate sorption (9 <= R d [L center dot kg - 1 ] <= 900), successfully modeled with a one -site Langmuir isotherm. Sorption data supports that (surface) precipitation occurs at higher ISA concentrations. The formation of stable Ca-ISA aqueous complexes promotes the incongruent dissolution of cement phases, altering of the overall Ca:Si ratio. The interplay between sorption and solubility phenomena must be considered for a correct interpretation of cement-ISA systems. | - |
