COMPLEX ADDITIVE FOR CONCRETE MIX, METHOD OF PRODUCTION OF COMPLEX ADDITIVE AND PRODUCTION LINE FOR REALIZATION OF THIS METHOD Russian patent published in 2007 - IPC C04B22/00 C04B24/24 B28C5/00 B28C9/02 C04B28/00 C04B111/20 

FIELD: construction engineering; manufacture of precast concrete and reinforced concrete products including underground products; monolithic house-building.

SUBSTANCE: proposed complex additive contains cement, powder-like superplasticizer C-3, alumino-silicate component in form of zeolite and micro-silica at the following ratio of components, mass-%: cement, 80-85; superplasticizer C-3, 2.0-3.5; micro-silica, 10-12; the remainder being zeolite. Method proposed for production of concrete mix includes grinding of components to specific surface of 4500-5000 cm²/g in disintegrator-type aerodynamic activator at rotational speed of 3000-6000 rmp; prior to grinding, components of concrete mix are loaded in cyclic-action mixer and are being mixed for 10-15 min. Production line proposed for realization of this method includes bins for storage and delivery of components which are interconnected with mixers for dry mixes by material lines via proportioners; said mixer is connected with aerodynamic activator by means of product lines. Specification gives versions of aerodynamic activator.

EFFECT: reduced consumption of cement at retained strength characteristics of cement due to enhanced activation of additive.
