Machine learning-driven analysis of nanoparticle performance on concrete mechanical properties
Bibliographic record
Abstract
Nanoparticles as raw material additive are substances that modify the concrete product. This study presents a comprehensive analysis of nanoparticle effects on concrete mechanical properties using advanced machine learning (ML) algorithms. We examine various nanoparticle types, including multi-walled carbon nanotubes (MWCNTs), graphene nanoplatelets (GNPs), nano-SiO 2 (silica), and nano-TiO 2 (titanium dioxide), investigating their impact on concrete’s flexural ( f b ), compressive ( f c ), and tensile ( f t ) strengths. We use ML algorithms such as decision tree (DT), Pearson correlation coefficient, and the hierarchical clustering algorithms to analyze their mechanical properties. Results show that there is a significant increase in mechanical strength when nanoparticles are incorporated into concrete. For example, adding nano-Fe 2 O 3 (iron oxide) can increase the control concrete sample of f c and f b from 105 MPa to 140 MPa and 16 MPa to 23 MPa, respectively. The study identifies five primary enhancement mechanisms: filler effect, nucleation site provision, pozzolanic reaction, nano-reinforcement, and C-S-H structure modification. However, Pearson correlation analysis reveals significant inconsistencies in strength improvements, with correlation coefficients ranging from 0.87 for tensile-compressive strength relationships to −0.26 for flexural strength improvements. The DT analysis reveals that nanoparticle concentration is the decisive factor in determining the improvement of concrete strength. On the other hand, the hierarchical clustering analysis identifies distinct groupings of nanoparticles based on their enhancement mechanisms, with MWCNTs forming an independent cluster due to their unique concrete f b (23 MPa) and f c (140 MPa) strengths. In addition, the cost analysis reveals that nanoparticle additions can improve concrete qualities, but their selection and dosage optimization should be considered to balance performance increases with economic viability in practical use. This research provides useful information for developing optimized nanoparticle-enhanced concrete formulations while highlighting the complexity of strength enhancement mechanisms.

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.
