AbstractAbout AuthorsReferences
The article is devoted to the study of hardening processes of a corrosion resistant, cementless building material on the basis of tridymite-cristobalite binder in the process of thermal treatment. The presence of a very narrow temporal optimum is shown; processes proceeding at various temporal stages of hardening are described; a description of all the curve knees of strength gain is made. The negative impact of cations Al+3 on the hardening process due to a significant reduction in the silica solubility and a significant increase in the duration of hydrothermal treatment on the strength characteristics of the finished material is also revealed.
