Mechanical Properties of Tunnel Muck with Fly-Ash Geopolymer
Figure 7
Pictures of geopolymer samples after uniaxial compression tests. Each row has the same Mfa/Mtm values, which are 1 : 3, 1 : 2, and 2 : 3 from the first to the third row, respectively. Each column has the same values, which are 1 : 8, 2.0, and 2.2 from the first column to the third column, respectively. Mliquid/Msolid ratios of each raw vary among 0.14, 0.16, and 0.18. The NaOH concentrations of each row vary among 8, 10, and 12. The details of the Mliquid/Msolid ratios and NaOH concentration can refer to Table 2.
