FIELD: hydraulic and industrial building, particularly to create fill ground structures, dams, motor roads, stacks and bases thereof.
SUBSTANCE: method involves preparing base for dam erection; filling dam body with ground and compacting thereof. The ground material is sludge taken from aluminum waste sludge storage facility and consists of electric filter dust and residues of gas cleaning and flotation operations. The sludge is prepared by dewatering thereof to obtain 0.4-0.5 humidity. Then the sludge is compacted to provide porosity of not more than 0.60.
EFFECT: provision of aluminum waste utilization, reduced costs.
