FIELD: manufacture of building products from concrete mixes with required quality and reduced specific consumption of material of equipment and labour input in process. SUBSTANCE: method includes separate supply into vessel of loose inert material and concrete mix, molding and removal of forms from articles. In doing so, prior to supply of loose inert materials into vessel placed into vessel is bottomless open from atop mold which is removed from vessel after its filling with concrete mix. Filling of vessel and mold is carried out correspondingly with dry loose inert material and dry concrete mix with subsequent wetting of the latter after removal of mold from vessel. Prior to supply of dry loose inert material arranged in vessel are additional molds located inside and/or outside of the main mold with subsequent filling of them with loose inert material or with dry concrete mix of same or some other composition. Removal of forms from product is accomplished by removal of loose material from vessel. In addition, the invention offers a number of additional technological procedures with the aim to increase the efficiency of the offered method and to manufacture products of various configuration with finished or decorative surface. EFFECT: higher efficiency. 11 cl |
