The invention relates to the production of building materials, namely to methods for the preparation of pressed articles from powder raw mixtures. A method for the production of building brick by mixing of 3-10 wt. % of lime with quartz sand with addition of water and following pressing of articles. The method is characterized in that at mixing 1-10 wt. % of phosphogypsum dehydrate is added to the mixture, after that the treatment is carried out in the equipment, which provides force mechanical effect, expressed in its multiple smashing and milling for 1-1000 cycles, whereby the equipment provides force mechanical influence to the mixture with the pressure from 0.1 to 2 MPa. The method provides the preparation of durable brick without treatment thereof in autoclave. |
