RAW MIX Russian patent published in 1999 - IPC

FIELD: grouting of cracks in alls of buildings and cracks in weak coal strata in faces, and cracks from which radiation rays of γ-irradiations emanate; manufacture of outer shells of lead containers for storage and transportation of radioactive waste. SUBSTANCE: raw mix comprises (wt %): caustic magnesite, 15-21.5; ground blast furnace main granular slag; ground blast furnace dust or gas purification slime 9-30.0; solution of bischofite with density of 1.3 g/cubic cm (calculated for MgCl₂, 9.3-11.16; alumosilicate additive (waste resulting from mechanical cutting of decorative slides on surface of crystal glass products, 1.0-5.0; water, with chemically bonded bischofite taken into account, the balance. EFFECT: higher water resistance, mobility and viability without decrease of compression strength and weight weakening coefficient when γ- irradiation occurs, and mix does not require heating. 4 tbl
