  • A strong alkali is needed to partially or entirely dissolve the silica and alumina available in the source materials.

    “According to Malkawi et al. [105], a strong alkali is needed due to the alkali activator’s function, which is required to partially or entirely dissolve the silica and alumina available in the source materials as explained in details in the polymerization mechanism [74,78,101,106].”

    From Potential of Soil Stabilization Using Ground Granulated Blast Furnace Slag (GGBFS) and Fly Ash via Geopolymerization Method: A Review (2022) · cites this paper as [101]

    The Discussion (p. 6) says NaOH or Na2SiO3 activators promote dissolution and may cause Si and Al to leach from the soil. The paper uses a strong NaOH solution (Alkali activator, p. 2), but it does not establish that a strong alkali is necessary or that silica and alumina dissolve entirely. (LLM, conf=0.84)

    Experimental — accuracy not yet measured

  • 10 M NaOH solution is suitable for Class F and Class C fly-ash-based geopolymer.

    “The researcher found that 10 M NaOH solution is suitable for Class F and Class C fly-ash-based geopolymer, respectively [51,74,101,107,108].”

    From Potential of Soil Stabilization Using Ground Granulated Blast Furnace Slag (GGBFS) and Fly Ash via Geopolymerization Method: A Review (2022) · cites this paper as [101]

    The Conclusions (p. 8) report strength gains using 10 M NaOH, but the binder studied was olivine in a silty-clay soil mixture. The paper does not establish that 10 M NaOH is suitable for Class F or Class C fly-ash-based geopolymers. (LLM, conf=0.88)

    Experimental — accuracy not yet measured

  • NaOH solution contains and provides hydroxide ion (OH-) and sodium ion (Na+), mainly responsible for the dissolution of aluminosilicate source materials and the polymerization process of geopolymer.

    “It contains and provides hydroxide ion (OH-) and sodium ion (Na+), mainly responsible for the dissolution of aluminosilicate source materials and the polymerization process of geopolymer [74,78,82,83,99,100,101].”

    From Potential of Soil Stabilization Using Ground Granulated Blast Furnace Slag (GGBFS) and Fly Ash via Geopolymerization Method: A Review (2022) · cites this paper as [101]

    The Alkali activator section (p. 2) identifies aqueous NaOH containing Na+ as the activator. The Discussion (p. 6) links NaOH and/or sodium silicate to dissolution and subsequent alkaline activation, while the Introduction (p. 1) describes polycondensation involving aluminosilicates and alkaline ions. The paper does not specifically identify OH− and Na+ together as the ions mainly responsible for both dissolution and geopolymerization. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
