FIELD: construction materials.

SUBSTANCE: invention relates to the industrial production of building materials and can be used in building blocks manufacture intended for the construction of low-rise buildings and cottages. The method includes mixing 32.5-34.7 wt. % binder, 30.0-35.0 wt. % of rice husk, 3.1-3.3 wt. % mineral filler and 1.0-1.2 wt. % of the hardening accelerator followed by forming, curing and drying. In this case, the mixing of ingredients is carried out in three stages. At first stage, the hardening accelerator is connected to 3,4-4,2 wt.% of the foaming agent and stirred for 20 to 30 minutes. At second stage, the resulting solution is combined with 25.0-26.6 wt.% sugar beet tops pre-dried at a temperature of 60 to 70°C for 40 to 45 minutes and crushed to a particle size of 0.8 to 1.0 mm and kept for 30 to 40 minutes with continuous stirring. At third stage, the resulting mixture is combined with mixture of binder, rice husk and mineral filler and mixed for 10 to 15 minutes.

EFFECT: increase in operational characteristics and expansion of materials range for building blocks.
