Figure 11.

Optical images of polished section surfaces of GSyl06ls prepared by adding 0.06 wt % of Si⁰ to hybrid geopolymeric slurry and allowing the foaming process to occur in a 10-dm³ mold. The samples shown were obtained from the core section of one of the specimens prepared in production scale. The stress–strain curve collected for 50 × 50 × 50-mm³ specimens (obtained as described in the text) is shown in Figure 9B (in magenta).
