METHOD OF MANUFACTURE OF LIGHT COMPOSITE AGGREGATE FOR CONCRETE Russian patent published in 2018 - IPC C04B18/24 C04B20/10 

FIELD: construction.

SUBSTANCE: invention relates to the construction and industry of building materials, in particular to methods for manufacturing lightweight composite aggregates for concrete. Method of manufacturing a light composite aggregates for concrete includes the manufacture of core aggregate by softening waste paper in 10 % solution of liquid glass, drying of the core for one hour at 110 °C, formation of a shell on the surface of the core by rolling it in a granulator in a mixture obtained by the joint milling of tripoli powder, Portland cement and high-strength separated gypsum, when moistened with 20 % aqueous solution of liquid glass, drying of the prepared aggregate at a temperature of 40 °C.

EFFECT: decrease in bulk density and thermal conductivity with sufficient strength of the aggregate.
