METHOD OF PRODUCING SYNTHETIC POROUS AGGREGATE Russian patent published in 2010 - IPC C04B20/00 C04B14/10 

FIELD: chemistry.

SUBSTANCE: invention relates to production of synthetic porous aggregates for concrete. The method of producing synthetic porous aggregate involves preparation of clay material and fuel, moulding semi-finished products, drying and burning. Mouldable clay material is laid in at least two 20-30 mm thick layers. A 3-5 mm thick fuel layer is placed between the layers of clay material. Moulded semi-finished products are dried to moisture of 2-5%. The semi-finished products are crushed and fractionated after burning. A version of the method of producing synthetic porous aggregate is described.

EFFECT: simple technology of producing porous aggregate.
