THE INFLUENCE OF TEMPERATURE AND COMPOSITION ON MODELED MORTARS

摘要

The study presents the results of modeled mortars prepared from the combination of lime and thermally treated clay as a substitute for the fragmented ceramics used in the past. The influence of the temperature of lime burning and ceramic firing is decisive for the products of their thermal treatment. The results of the final products of the prepared mortar matrices influenced by low temperature of treatment were compared with ancient mortar using modern analytical methods. The study was focused on alumina-silicates in calcareous surroundings and on the identification of the bonds between all components. The principle seems to be the coordination of aluminum ions to oxygen and its behavior of netting with silicon in aqueous alkali conditions.
