PROCESS OF PRODUCTION OF COMPOSITE BINDER ( VERSIONS ) Russian patent published in 2003 - IPC

FIELD: production of building materials, production of light-weight concrete on porous aggregates. SUBSTANCE: process of production of composite binder employs pearlite as basic component in composite binder. Process includes comminution and mixing of components. Crystalline pearlite is used as pearlite, it and other components are comminuted separately and then mixed. Before mixing crystalline pearlite is subjected to cathode-ray activation with following proportion of components, mas.%: crystalline pearlite, 54.0-70.0; quick lime, 30.0-46.0. EFFECT: increased hydraulic activity of pearlite and strength of binder, diminished ecological load on environment. 2 cl, 1 dwg, 2 tbl
