## 3 Experimental Regime
### Analysis of Adhesion Strength by Adhesion Area  
#### 3.6.1 AR 60 \(\pm\) 2% Specim  
For the AR 60 \(\pm\) 2% specimens, out of the 40 tile pieces of the specimen, 14 (35% of the entire tile surface) of No.1 specimen showed stable adhesion, and the pieces that satisfied the ISO standard requirement (0.5 N/mm\({}^{2}\)) was 7 (50% of the stable attached pieces). For the No. 2 specimens, 14 (35% of the entire tile surface) showed stable adhesion, and 13 (92.9% of the stable attached pieces) satisfied the ISO standard requirement. For the No. 3 specimens, 16 pieces (40% of the entire tile surface) showed stable adhesion, and the pieces that satisfied the ISO standard requirement were 10 (62.5% of the stable attached pieces). The overall average adhesion strength of the No.1, No. 2, and No. 3 specimens were, respectively, 0.21 N/mm\({}^{2}\), 0.28 N/mm\({}^{2}\), and 0.26 N/mm\({}^{2}\), resulting in a comprehensive average of 0.25 N/mm\({}^{2}\). When considering the average of only the pieces with stable adhesion, the average was, respectively, 0.59 N/mm\({}^{2}\), 0.81 N/mm\({}^{2}\), and 0.66 N/mm\({}^{2}\), resulting in a comprehensive average of 0.69 N/mm\({}^{2}\). Refer to Table 7 and Figure 14 below (sections marked with 0.00 represent tiles with cavities where there was no cementitious adhesive support for the tile or cases where measurement was not impossible).
