FIELD: chemistry; power engineering; ecology. ^ SUBSTANCE: invention relates to allocation of liquid radioactive wastes and meant for applying in atomic power engineering and radiochemical productions for solidification of radioactive solutions and pulps. The composition for cementing liquid radioactive consists of portland cement and natural aluminium silicate materials (argosite, vermiculite, parclay, clinoptilolite). Low lime ash of combined heat and power station is used as an active mineral admixture. Superplasticising agent C-3 is used as a plasticiser. The composition consists of portland cement, natural aluminium silicate materials, superplasticising agent C-3, low lime ash of combined heat and power station at the particular ratio of these components. ^ EFFECT: decrease of compound temperature during solidification due to decreasing heat liberation. |
