METHOD OF PRODUCING GRANULAR AGGREGATE FOR AUTOCLAVE HARDENING SILICATE ARTICLES Russian patent published in 2011 - IPC C04B28/18 C04B20/00 C04B111/20 

Abstract RU 2433976 C1

FIELD: chemistry.

SUBSTANCE: invention relates to production of construction materials and can be used when making silicate wall structures - lime-sand brick, tiles, blocks, wall panels, which are subjected to autoclave treatment during hardening. The method of producing granular aggregate for autoclave hardening silicate articles, consisting of a core and cladding, involves formation of a core in the presence of liquid glass from a mixture of jointly ground foamed pearlite and sodium hydroxide, rolling the cladding on the surface of the core from jointly ground unslaked lime with sodium silicofluoride, curing the granules in a microwave field with specific power consumption of 53-82 J/cm3.

EFFECT: shorter production time, high activity of the granular aggregate, low heat conductivity, improved strength properties of autoclave construction articles.
