METHOD OF MOLDING PARTS AND CONSTRUCTIONS FROM CONCRETE Russian patent published in 1999 - IPC

FIELD: manufacture of building materials. SUBSTANCE: invention aims at working out a method for molding parts and constructions from concrete which would allow usage of binding materials to be reduced and, simultaneously, standard strength of concrete to be preserved owing to approaching water-to-cement ratio in mixes utilized to its theoretical value. In some cases, method allows utilization of falseworks and molds to be avoided. According to method, solid components of concrete mix are laid electrostatically in dry state on forming wire-mesh frame. In the course of molding parts, precipitating components are continuously wetted in dosed mode or process is conducted periodically when layered electrostatic precipitation of solid components of concrete mix and wetting are alternated. Precipitated layers of dry components of concrete mix can be wetted with atomized water containing, for example, surfactants. Water steam can also be employed. EFFECT: enhanced process efficiency. 5 cl
