FIELD: building materials.
SUBSTANCE: invention relates to the production of building materials, namely to methods for making limestone building materials and can be used for production of walling materials. Method of production walling materials includes the preparation of a raw mix, which contains 95–97 mass % of limestone and 3–5 mass % of lime-litter. Molding and carbonization of products are carried out. In this case, the dry raw mix is granulated in a gaseous medium with a carbon dioxide content of 50–70 % before pressing. As a granulation liquid, lime milk with a density of 1,050–1,150 MPa is used. Products with subsequent curing are pressed.
EFFECT: technical result is the obtaining of high physical and mechanical characteristics of the products.
