Abstract
The development of techniques for concrete repair will reduce environmental impacts associated with concrete usage by extending the lifespan of existing structures. This study investigates microbially induced carbonate precipitation (MICP) for treating fractured concrete. Our results demonstrate the excellent penetrability of MICP with precipitates well-distributed along core length. Some individual treatment cycles resulted in – one order of magnitude reduction in core permeability. Treatment efficiency is shown to be dependent on fracture network characteristics, i.e. number of fractures, fracture orientation, initial hydraulic aperture. Furthermore, bridging of precipitates across fracture surfaces resulted in a recovery of 26–50% of initial tensile strength.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
