Study on the Influence of Different Aqueous Solutions on the Mechanical Properties and Microstructure of Limestone
Bibliographic record
Abstract
Abstract Uniaxial and triaxial compression tests were carried out on limestone samples immersed in distilled water and pH = 2 solution for 80 days to investigate the influences of aqueous solutions on the mechanical properties of limestone. Scanning electron microscopy and image recognition techniques were employed to analyze the morphology of limestone before and after immersion in aqueous solutions. The test results show that the peak stress and elastic modulus of the limestone specimens were reduced while the Poisson’s ratios were increased after 80 days of soaking. A series of chemical reactions take place between water and rock samples during the process of soaking. Energy-dispersive spectrometer analysis results showed that the content of calcium in the surface of the sample decreases after soaking, while the contents of aluminum, magnesium, and silicon are increased. From the image analysis results, it is demonstrated that the number and area of microscopic pores of the sample after immersion increased. The physical-chemical actions between the aqueous solutions and the samples lead to the deterioration of the mechanical properties of the rock.

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.
