FIELD: construction.
SUBSTANCE: method for manufacturing wood concrete consists in pre-treatment of wood aggregate in the 4% solution of sodium hydroxide at the temperature of 50-60°C and simultaneous ultrasonic treatment with the frequency of 30-40 kHz for 20-30 minutes; then, after the NaOH solution is drained, the wood aggregate is flushed with water.
EFFECT: increasing physical and mechanical characteristics of products.
