Properties measured for IbuMCC and IbuMannitol formulations. The wall friction angle is an input parameter for the model and has been estimated based on literature values, e.g. (Nesarikar et al., 2012).
| IbuMCC | IbuMannitol | |
|---|---|---|
| True density (g/cm3) | 1.299 | 1.269 |
| Effective angle of internal friction (δE) | 44° ± 2° | 36° ± 1° |
| Compressibility factor [K] (out-of-die) | 7.84 | 10.29 |
| Pre-consolidation relative density [γ0] (out-of-die) | 0.504 | 0.548 |
| Angle of wall friction (ΦW) | 15° | 15° |
