Original Abstract

Processes of structure formation taking place in the interfacial transition zone „cement paste – aggregate“ have been studied on a variety of cement model systems. The results of study suggested drawing a conclusion that depending upon contents of components capable to actively interact with alkalis in the presence of reactive SiO2 in cements could be both of constructive and destructive character. So-called "constructive processes" are attributed to binding the corrosion reaction products with the formation of the alkaline aluminosilicate hydrates. The results of study have been taken as a base in developing a mechanism of preventing the alkali-aggregate reaction in the alkali activated cement concretes through the introduction of additional quantities of Al2O3-contamining substances.
