UCS results and carbonate content in the specimens treated with three different EICP solutions.
| EICP Solution | Test No. | Peak Strength* (kPa) | Mean Strength (kPa) ± STDV. | CaCO3 (%) | Mean CaCO3 (%) ± STDV. |
|---|---|---|---|---|---|
| Solution 1 (Baseline EICP) | 1 | 133 | 138 ± 18 | 1.63 | 1.20 ± 0.37 |
| 2 | 158 | 0.98 | |||
| 3 | 124 | 0.99 | |||
| Solution 2 (Modified EICP) | 1 | 1817 | 1745 ± 83 | 0.82 | 0.93 ± 0.21 |
| 2 | 1654 | 0.79 | |||
| 3 | 1763 | 1.17 | |||
| Solution 3 (Modified EICP) | 1 | 1000 | 1112 ± 247 | 0.57 | 0.59 ± 0.20 |
| 2 | 1396 | 0.71 | |||

*Peak strength is the maximum axial compressive stress that each specimen can withstand during a UCS test.
