Water absorpion coefficients (WACs) of Schlaitdorfer sandstone and Auer limestone for untreated and treated specimens and relative WAC increase post-consolidation.
| Treatment | WAC (kg/m2⋅h0.5) | WAC Increase 1 (%) | ||
|---|---|---|---|---|
| Schlaitdorfer Sandstone | Auer Limestone | Schlaitdorfer Sandstone | Auer Limestone | |
| Sound | 3.25 ± 0.86 | 9.31 ± 0.3 | - | - |
| Aged | 5.91 ± 1.24 | - | - | - |
| NL | 3.62 | 8.87 | −39 | −5 |
| NC | 3.36 | 9.62 | −43 | 3 |
| DAP | 2.90 | 8.78 | −51 | −6 |
| NL-DAP | 3.06 | 8.99 | −48 | −3 |
| NC-DAP | 2.61 | 9.3 | −56 | 0 |
| DAP-NL | 3.10 | 8.1 | −48 | −13 |
| DAP-NC | 3.98 | 8.56 | −33 | −8 |
1 For Schlaitdorfer sandstone, the WAC increase was calculated comparing the values of the treated samples with the aged untreated samples; for Auer limestone, with the sound untreated samples.
