FIELD: waste processing and recycling.
SUBSTANCE: invention relates to localisation of liquid radioactive wastes and is intended for use in nuclear power engineering and at radiochemical plants for solidification of radioactive flows and pulps. Composition for cementing liquid radioactive wastes consists of portland cement and natural aluminum silicate materials (bentonite, vermiculite, kaolin, klinontilolit). Active mineral additive used is graphite, which is a production waste in nuclear industry. Plasticiser used is superplasticiser C-3. Certain ratios of components are maintained in composition.
EFFECT: invention reduces cost of composition and enables to recycle wastes formed in nuclear industry.
