FIELD: building.
SUBSTANCE: present invention relates to building, namely to manufacture of building materials and structures, and can be used in production of sulphur concrete mixtures and products. The method for producing a sulphur concrete mixture for manufacture of products or structures includes heating inert materials, mixing with sulphur, melting the sulphur and forming a sulphur concrete mixture. The method includes two stages, wherein at the first stage, sulphur is crushed and simultaneously mixed with inert and modifying additives at an ambient temperature, resulting in a cool dry sulphur concrete mixture, and at the second stage, the mixture is melted by heating to a temperature of 140 to 160°C, or sulphur is introduced into the prepared cold mixture of inert and modifying additives in the form of granules, and then the mixture is heated to a temperature of 140 to 160°C and mixed.
EFFECT: increase in the efficiency of use of sulphur concrete due to the reduction in the power consumption, increase in the strength of products, manufacturability of preparation, and expanded area of application in building due to the possibility of preparing a "cold sulphur concrete mixture" at dry mortar plants and concrete product plants, as well as creation of a method for manufacturing sulphur concrete products as close to the conditions of existing manufactures of concrete products and building sites, including remote ones, as possible.
