FIELD: construction.
SUBSTANCE: method of the thermal treatment of silicate decorative brick consists in charging of raw bricks into an autoclave, heating of the raw bricks by blowdown with live steam for 0.5 hour at atmospheric pressure to a temperature of 45-50°C, soaking of the raw bricks in the heated autoclave at atmospheric pressure without steam supply for 15 min., subsequent pressure and temperature rise, soaking at the maximum pressure and temperature, reduction of pressure and discharge of the items.
EFFECT: improved quality of bricks by the increase of their strength and preservation of specified colour and appearance of a decorative silicate brick.
