In addition, the compositions of the products in Fig. 11(e) and Fig. 11(f) are consistent, but the mortar permeable layer exhibits expansion cracks, while the surface layer is intact.
In addition, the product composition in Figure 11 (E) and Figure 11 (f) is the same, but the mortar penetration layer has expansion cracking, while the surface layer is intact.
In addition, the composition of the products in Figure 11(e) and Figure 11(f) is the same, but the penetration layer of mortar is expanded and cracked, while the surface layer is intact.
