FIELD: manufacture of building materials; manufacture of building parts, articles and structures for encapsulation of radioactive and highly toxic waste.
SUBSTANCE: proposed composition contains the following components, mass-%: sulfur, 53.27-53.32; ground quartz sand at specific surface of 180 m2/kg, 45.4-45.50; kerosene, 1.06-1.07; rubber CKДH-H, 0.22-0.11. Encapsulation is carried out by combining the composition with waste followed by hardening. Containers may be also made from composition for burying the waste in geological formation.
EFFECT: reduced water absorption at retained high compressive strength.
