Nevertheless, incomplete geopolymerisation is still observed in this sample. Figure 7 d illustrates a geopolymer sample with ratio S/L 1.75 and Na 2 SiO 3 /NaOH 1.5 and the maximum compressive strength (11.5 MPa) was obtained. For this mix design with Na 2 SiO 3 /NaOH more than 2.0, the geopolymer samples were unable to be prepared due to low ...

The raw mix was dry-homogenized. For the synthesis, we used finely ground limestone filler, with a maximum residue on the 200 μm sieve of 2% and of 20% on the 90 μm sieve. The clay, gypsum, and bauxite were previously crushed and ground in the planetary ball mill (Fritsch Pulverisette planetary ball mill, Idar-Oberstein, Germany).
