Kiseleva S. Energy and resources saving technology of the silicate brick

An object is phases formation processes in lime-sand mixture at hydrothermal treatment. Aim of the work is revelation of conformities to law and features of phases formation processes at hydrothermal treatment of lime-sand products for development of energy- and resource saving technology of the silicate brick. Methods experimental: x-ray analysis, differential thermal and differential thermogravitation analysis, raster electronic microscopy; theoretical: thermodynamics analysis, kinetic researches. Theoretical and practical results: conformities to law of phases formation processes lime-sand mixtures with additions of industrial wastes and electrolytes and kinetic conformities to law of processes in lime-sand mixtures with complex addition have been determination; technology of silicate brick with the use of wastes of industry which allows to decrease pressure of autoclaving on 0,2 MPa as well autoclaving treatment time of articles on 2 h is developed. Novelty: scientific bases of technology of silicate brick with complex addition to lime-sand raw material mixture, that allows directionally to form a structure and properties of products at the energy saving parameters of autoclaving are created. Degree of introduction: research party of silicate brick is tested by "Ukrspecvagon", s. Panyutine; multitonnage party of silicate brick is made and tested on the "Severodonetsk factory of build ceramics"; the results of researches are used in an educational process at teaching of disciplines "General technology of refractory non-metal and silicate materials", "Chemical technology of binders ". Industry of the use: industry of the autoclave silicate materials.
