Table 12
Raw material configurations and the measured mechanical indices of analogue materials.
| | Material ID | Raw material configuration | Measured mechanical index | | (the proportion of fine powder to aggregates) | (the proportion of barite sand to coarse aggregate) | (the mass ratio of anhydrous sodium silicate to aggregate) | Density
(g/cm3) | Young’s modulus
(GPa) | Compressive strength (MPa) | Tensile strength
(MPa) |
| | 1# analogue material | 30% | 50% | 3% | 2.855 | 0.286 | 6.058 | 1.469 | | 2# analogue material | 65% | 00% | 3% | 2.181 | 0.035 | 0.315 | 0.180 |

Note: the mass ratio of sodium fluorosilicate to anhydrous sodium silicate was 3 : 4 (this was the optimal value).
