Abstract

The paper covers the results of study of cavitation treatment on amorphization of kaolinite n the alkaline aluminosilicate dispersions of the “Kaolin—Na2O · nSiO2 · mH2O—NaOH—H2O” composition. The purpose of the study was to establish a possibility to substitute metakaolin in these dispersions for kaolin. The results show that amorphization of the kaolinite in the field of dynamic cavitation takes place at relatively low temperatures (below 60 °C) resulting in the formation of the properties of these dispersions that are comparable to those of the metakaolin-based dispersions. Above this, rheological and technological properties of the alkaline aluminosilicate dispersions of the “Kaolin—Na2O · nSiO2 · mH2O—NaOH—H2O” composition such as viscosity, shelf life, adhesion to concrete, metal and wood have considerably improved.
