Аннотация

In the present paper, the issues of studying the influence of complex activation of grouting fluid on
the structure and properties of the hardened cement paste and concrete are considered. The problem is relevant for
manufacturing of building materials. In the paper, there was used the method of applying in the concrete mix
composition of the elementary chemical substances undergone special physical treatment by means of
mechanomagnetic activation. For more profound study of the structure formation processes in the hardened cement
paste, the method of differential thermo gravimetric analysis has been used. As the research results have shown, the
concrete samples on the activated electrolyte solutions are characterized by improved strength. In addition, on the
base of differential thermo gravimetric analysis, it was proven that in the studied samples of the hardened cement
paste on the electrolyte solutions activated by the method of mechanomagnetic treatment, the less calcium hydroxide
and the more hydrated calcium silicate with amorphous and fine crystalline is formed. The obtained results for
cement composites could be applied when manufacturing effective binder for concretes and mortars in the
production of building materials and structures
