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.
Characteristics of metakaoline modified mortars applied on historic objects
Slížková, Zuzana
Samples of two lime-metakaoline plasters applied on historical walls in the Czech Republic a few years ago were investigated and analysed using optical and SE microscopy, EDS, XRD, and mercury porosimetry. Mechanical and other physical characteristics of small samples were also determined. Results and recommendation are presented in the paper.
