Batch number, designation, and description.
| Batch number | Designation | Description |
| 1 | Control-0% TDA | Control mix design, no TDA used |
| 2 |
100% TDA-2′′ | 100% replacement of coarse aggregate with TDA of size 2′′ (50 mm) |
| 3 | 17% TDA-2′′ | 17% replacement of coarse aggregate with TDA of size 2′′ (50 mm) |
| 4 | 10% TDA-2′′ | 10% replacement of coarse aggregate with TDA of size 2′′ (50 mm) |
| 5 | 10% TDA-2′′-NaOH Sol | 10% replacement of coarse aggregate with TDA of size 2′′ (50 mm). TDA dissolved in NaOH solution and both TDA and NaOH solution included in batch |
| 6 | 7.5% TDA-1′′-NaOH | 10% replacement of coarse aggregate with TDA of size 2′′ (50 mm). TDA dissolved in NaOH solution for 24 hours but solution not included in the batch |
| 7 | 10% TDA-2′′-Epoxy | 10% replacement of coarse aggregate with TDA of size 2′′ (50 mm). TDA treated with 2-part epoxy before mixing |
| 8 | 10% TDA-2′′-SF-R | 10% of coarse aggregate replaced with an equal volume of TDA size 2′′ (50 mm) and 20% of cement replaced with silica fume |
| 9 | 10% TDA-2′′-SF-A | 10% of coarse aggregate replaced with an equal volume of TDA size 2′′ (50 mm) and silica fume equal to 20% of cement added to the mix |
| 10 | 7.5% TDA-2′′-SF-A | 7.5% of coarse aggregate replaced with an equal volume of TDA size 2′′ (50 mm) and silica fume equal to 20% of cement added to the mix |
| 11 | 7.5% TDA-1′′-SF-A | 7.5% of coarse aggregate replaced with an equal volume of TDA size 1′′ (25 mm) and silica fume equal to 20% of cement added to the mix |
| 12 | 7.5% TDA-1′′ | 7.5% of coarse aggregate replaced with an equal volume of TDA size 1′′ (25 mm) |
