METHOD FOR MANUFACTURING OF CONCRETE STONES OR CONCRETE PLATES Russian patent published in 2006 - IPC B28B3/00 B28B11/00 B05D1/28 

FIELD: processes and equipment for manufacture of differently shaped and sized concrete stones or plates.

SUBSTANCE: method involves providing vibrational compaction of mold filled with concrete and punches having surfaces corresponding to surfaces of stones or plates; subjecting concrete stones or concrete plates to at least one subsequent process followed by hardening process. Subsequent process for treating surface of concrete stones or concrete plates includes treating said stones or plates by means of materials attached to instrument and made in the form of brush or broom, said materials being fabric, sponge, nonwoven material, felt, soft rubber or plastic. Materials are united into one or number of rows and secured on surfaces, which are guided above surface of concrete stones or concrete plates in any direction, with oscillating and/or rotating motion being imparted to said materials. During treatment, said materials and/or concrete stones or concrete plates are preferably wet or wetted with liquid such as water or dispersion. Before sequential treatment process, surfaces of concrete stones or concrete plates are painted in different colors using liquid paint. Concrete stones or concrete plates manufactured by method have treated surfaces with fixed concrete particles. Concrete stones or concrete plates have colored and/or shiny surface.

EFFECT: provision for producing articles having variously colored surfaces, increased compaction of concrete particles and reduced roughness of article surface.
