Developments strenght attained of the system metakaolinite – podium aluminite - quartz
Hájek, Pavel ; Koloušek, D. ; Andertová, J.
/: Geopolymer reactions have much in common with diagenetic transformations of the sedimentary rocks. Inside of laboratory conditions occur of geopolymer masses in alkali reaction of metakaolinite to sodium aluminate (Fastex 81) and quartz. As a result reaction is rise the zeolite phase (zeolite A) inside of relevant substance. The zeolite phase, temperature dressing materials and hydrothermal exposition influence developments strength. Results reaction were confirmed by means of X – ray diffractometry and SEM.
