Description of moisture conditions
| Condition | Method |
|---|---|
| AD | Specimens were placed in a controlled environment of 23 ± 3°C and RH of 50–55% for 4 d. All faces were exposed to similar conditions and adequately ventilated |
| OD | Specimens were fired in an oven at 100 ± 5°C until the difference between two consecutive weighings, within 2 h, was ≤0·1% of the specimen weight |
| SA | Specimens were immersed in water at a temperature of 23°C for 2 d and tested in a wet condition (i.e. immediately after removal from water) |
