Table 3.
The major elemental (oxide) composition of the test binding materials and reference binder.
| BM | Elemental Oxide Composition of the BM (%) | CEC (meq/100 g) | ||||
|---|---|---|---|---|---|---|
| Al2O3 | SiO2 | K2O | CaO | Fe2O3 | ||
| AC | 18.0 | 26.0 | 0.22 | 0.79 | 45.31 | 27.2 |
| KC | 25.0 | 31.0 | 0.01 | 0.24 | 39.73 | 18.8 |
| CC | 32.8 | 61.3 | 0.63 | 0.49 | 2.14 | 7.0 |
| MC | 24.0 | 34.8 | 0.52 | 0.54 | 36.1 | 15.4 |
| VA | 15.0 | 22.0 | 8.78 | 14.9 | 26.2 | 25.4 |
| RA | 0.5 | 75.7 | 9.54 | 1.71 | 0.59 | 27.2 |
| R | 5.1 | 49.0 | 6.99 | 13.4 | 19.8 | 38.9 |
In this and subsequent tables, BM = TBM and R, TBM = test binding materials, R = reference materials and CEC = cation exchange capacity.
