AbstractAbout AuthorsReferences
The process of nanosystem forming during interaction alkali activator ions with particles of ground-granulated blast furnance slag have been discussed. The effect of positive and negative hydration of ions on the properties and structure of water solution has been analyzed. Taking into account structural changes of mixing liquid, optimal concentration of activators were selected. It was shown that activators having as a part of ions with negative hydration promote to increase as curing rate and 28-age strength of stone. The strength of samples prepared from GGBFS and KOH solution is 27% higher, then strength of sample on a base of NaOH solution (under normal curing conditions).
