CONCRETE MANUFACTURE PROCESS Russian patent published in 2004 - IPC

FIELD: manufacture of building materials.

SUBSTANCE: concrete, which may be used in manufacture of structures and parts showing high dielectric and shock-adsorbing properties, is obtained by treating mineral aggregate with binder, forming framework, filling hollows thereof with building mortar, and hardening. Framework is formed by gluing mineral aggregate grains with high-fusing bitumen, after which surface of the framework is additionally treated with fusible bitumen and, before hardening, subjected to heat treatment for 1-1.5 h at melting temperature of fusible bitumen.

EFFECT: enhanced dielectric and shock-adsorbing properties of concrete.
