Macroporous geopolymers designed for facile polymers post-infusion
Bibliographic record
Abstract
Highly porous geopolymers suffers from poor mechanical properties; typically intrinsic brittleness, low compression strength and very weak toughness. Geopolymers were designed so that they can be reinforced by incorporating a low viscosity polymeric resin through a facile post-infusion process. Porosity in the range of 100–4700 μm was generated by decomposition of hydrogen peroxide and large expanses of open porosity was obtained by the addition of small amounts of saponified canola oil as a surfactant. Geopolymers with high open porosity (~60 vol%) and low compression strength (<1.5 MPa) were infilled with an unsaturated polyester resin. High amounts of resin (>75 vol% with respect to the open porosity) were incorporated and polymerized within the porous geopolymer framework. As a result, compressive strength of geopolymers composites can be increased as much as 40 times despite poor interfacial adhesion prevailing between inorganic and organic phases.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
