2.2.3. Mortar Mix Design without TX10 Treatment

Table 6 shows the experimental mix design of SWCNT-added mortars without treatment of TX10 and the quantities of the materials. The mixes were named according to: SWCNTXN, where SWCNT represents the material SWCNT; X stands for the concentration of SWCNTs with 0, 2, 4, 6 representing 0.00 wt%, 0.02 wt%, 0.04 wt%, 0.06 wt% respectively; and N represents no SAA added.

Table 7 shows the experimental design of MWCNT-added mortars without treatment of TX10 and quantities of each materials.



Rhenofit® CNT-3 and Rhenofit® CNT-2 are water-based CNT suspensions; 99.4% and 96% of the solutions is water, respectively. Thus, during preparation of specimens, the water contained in the Rhenofit® CNT-3 and Rhenofit® CNT-2 should be subtracted. Tables 6 and 7 show the mix proportion of the materials. Since Rhenofit® CNT-3 and Rhenofit® CNT-2 are water-based CNT suspensions, as the concentration of SWCNTs and MWCNTs increased, less water was needed. This was to keep the quantity of water in mortars uniform.

Mortars with no CNTs were set as control samples, to compare with CNT-containing mortars.
