Sensitivity analysis scenarios for EICP, PC, and MICP treated sand at various target UCS values.
| Target unconfined compressive strength (MPa) | Percentage by dry weight of sand for the different constituents | ||||
|---|---|---|---|---|---|
| EICP (%) | PC (%) | MICP* | |||
| Urea | CaCl2 | Enzyme | Cement content | ||
| 0.73 | 0.91 | 1.82 | 3.64 | 9.5 | LCA results were directly reported in terms of MPa of UCS from Deng et al.46 |
| 1.50 (baseline) | 1.115 | 2.23 | 4.46 | 14 | |
| 2.40 | 0.046 | 0.091 | 0.182 | 15 | |
*Adjusted to current FU (treatment of 1500 m3 soil volume).
