| Specimen | Frost damage | Freezing-thawing cycle (cycle) | Weight falling height H (m) | Measured impact velocity V (m/s) | Input energy Ek (kJ) |
| N-H0.5 | Without damage | — | 0.5 | 3.18 | 1.52 | N-H1.0 | | 1.0 | 4.51 | 3.05 |
| D-H0.5 | With damage | 872 | 0.5 | 3.15 | 1.49 | D-H1.0-1 | | 1.0 | 4.51 | 3.05 | D-H1.0-2 | | 1.0 | 4.44 | 2.96 |
