Sažetak
Geopolymers with different chemical composition have been prepared at 70oC. The processes of geopolymerization have been investigated insitu by simultaneous WAXS and SAXS measurements. The prepared samples were tested for thermal resistance by application of TG/DTA, and for mechanical compressive strength. WAXS shows that the developed structure of the geopolymers is mostly amorphous, and its structural arrangement strongly depends on the chemical composition of the used suspension. During the evaluation process the SAXS data were analyzed by using a fractal approach. The fractal dimensions are in the range from 2.2-3.3. The developed geopolymeric structure was confirmed by FTIR. The thermal and mechanical properties of the developed geopolymer structure show a very high thermal resistance up to 1000oC and a compressive strength up to 42MPa.
