CONCRETE RADIATION PROTECTION MIXTURE

摘要

The invention relates to the production of construction materials and can be used for producing concrete mixture used for building constructions exhibiting radiation protection properties. The inventive concrete radiation protection mixture comprises soluble glass, alkaline fluorosilicate and a fine aggregate in the form of a lead-containing broken glass with fractions ranging from 1.25 to 0.63 mm, from 0.63 to 0,32 mm and from 0.32 to 0.14 mm, a filler in the form of powdered glass of kinescope funnel whose specific surface area ranges from 3500 to 5000 cm<2>/g, a coarse aggregate in the form of broken glass of kinescope tubes with fractions ranging from 5 to 25 mm and from 2.5 to 1.25 mm and a fine aggregate in the form of broken glass of kinescope tubes, according to the following ingredient ratio: 5-8 mass % of soluble glass, 0.01-0,1 mass % of alkaline fluorosilicate, 20-25 mass % of powdered glass of kinescope tubes, the coarse aggregate in the form of broken glass of kinescope tubes with the following fraction makeup: 25-30 mass % of 5-25 mm and 10-15 mass % of 2.5-1.25 mm, and a fine aggregate in the form of broken glass of kinescope funnels having the following fraction makeup: 9-12 mass % of 1.25-0.63 mm, 9-12 mass % of 0.63-o.32 mm, 9-12 mass % of 0.32-0.14 mm, the rest being water. The inventive concrete mixture can be used at a temperature ranging from 60 DEG C to +200 DEG C, the production thereof does not require sophisticated technology and makes it possible to recycle waste glass of kinescope.
