Pearson’s correlation analysis results of grouting materials’ strength data.
| Data group | Pearson’s correlation coefficient | Flexural strength (MPa) | Compressive strength (MPa) |
| Group 1 (0–14 curing days) | 0.72 | 0.68 | Group 2 (3–14 curing days) | 0.82 | 0.54 |
| Appendix | Very strong correlation | >0.8, <−0.8 | Strong correlation | 0.6∼0.8, −0.6∼−0.8 | Moderate correlation | 0.4–0.6, −0.4∼−0.6 | Weak correlation | 0.2–0.4, −0.2∼−0.4 | Very weak correlation | <0.2, >−0.2 |
