Dotcenko J. Complex-activated silicate composites of reduced power consumption

The object of research - complex-highly mobile fine-grained mixture of activated, modified additives, and silicate composites heat-to-humidity hardening based on them; goal is the optimization of fine - grained high-mobility properties of activated mixtures of silica and composites heat-to-humidity hardening based on them by regulation of complex of various types of activations; methods -field experiments with the use of multifactor planning of the experiment to obtain the ES models. Field experiments and research carried out in several research laboratories: determination of physico-mechanical and construction performance properties according to standard procedures and characterization of structures at the departments of "building materials", "production of building structures" and "processes and devices in the technology of building structures". The construction and analysis of ES models were performed using a dialog system COMPEX and standard programs Microsoft Office; results - controlling the complex of various types of activations and their attendant technological effects realized in injection molding technology for high-mobility compounds, it is possible to obtain silicate composites of low intensity, with high physical-mechanical and construction performance properties; estimated ES models the impact of different types of activation on the activity and the pH of the mixture and a quantitative assessment of the contributions of different types of activations in complex; confirmed the rationality of using the proposed indicators to assess the contributions of the various types of activations and quality control of highly mobile mixes; on the basis of quantitative assessment of the impact of various types of activations, the ranking analyzed the properties of mixtures on the basis of ES-models; the mechanism of the complex effect of different types of activations and related technological effects on the structure and properties of silicate composites curing hardening, manufactured by molding technology, based on highly mobile fine-grained lime-silica mixture; introduced - with the release of an experimental batch with a volume of 45m3 of building blocks; the technological regulations on the production of calcium silicate composites curing hardening in the form of a hollow wall stones by size classes 390х190х188мм B10, B15 12.5 and a density of 1200-1400кг/m3
