| Property | Specimen code | RC | DC1 | DC2 | DC3 | AC1 | AC2 | AC3 | MC1 | MC2 | MC3 |
| Loss of strength of specimens kept in the less effective solution (%) | 10.0 | 16.0 | 26 | 63.0 | 2.0 | 38.4 | 22.0 | 10.8 | 34.0 | 22.8 |
| Loss of strength of specimens kept in the severe effective solution (%) | 18.5 | 21.0 | 50 | 46.0 | 21.4 | 7.30 | 31.0 | 14.6 | 20.8 | 29.0 |
| Loss of strength of specimens kept in the very severe effective solution (%) | 25.4 | 41.4 | 51 | 67.5 | 22.0 | 22.7 | 0.30 | 10.3 | 39.0 | 20.2 |
