FIELD: construction.
SUBSTANCE: invention relates to production of building materials, namely to methods of manufacturing building materials, and can be used for production of wall materials. Method of manufacturing wall materials includes granulating a raw mix including sand, pressing and hardening of products. Raw meal contains 70–90 % by weight of fine-grained quartz sand and 30–10 % by weight of clay. And before granulation, sand and clay are subjected to mechanoactivation in a shock-type mill at a particle collision rate of 100–150 m/s. In this case knurling of the cement layer is performed before pressing.
EFFECT: increasing the strength of products due to formation of a crystallization-condensate structure.
