| Concentration (%) | MC (%) | D (kg/m3) | WA (%) | TS (%) |
| 5 | 7.83 ± 5.72 | 689.92 ± 21.20 | 30.98 ± 2.94a | 7.73 ± 1.12a |
| 3 | 8.60 ± 3.08 | 688.90 ± 20.61 | 32.03 ± 1.24a | 8.36 ± 1.07a |
| 1 | 8.94 ± 4.75 | 686.39 ± 22.37 | 32.42 ± 1.78a | 8.65 ± 1.16a |
| 0 | 9.89 ± 1.98 | 685.12 ± 29.81 | 38.83 ± 2.89b | 10.95 ± 0.90b |
| Average | 8.77 ± 3.88ns | 687.58 ± 23.50ns | 33.57 ± 2.21 | 8.92 ± 1.06 |
The letter ns indicates insignificant differences, and different letters (a and b) indicate significant differences between the percentage of moisture content, density, water absorption, and thickness swelling as obtained from ANOVA, p < 0.05, followed by Duncan’s new multiple range test.
SiO2: silicone dioxide, MC: moisture content, D: density, WA: water absorption, TS: thickness swelling, ANOVA: analysis of variance.
