COMPOSITION FOR MANUFACTURING BUILDING PRODUCTS Russian patent published in 2000 - IPC

FIELD: building materials industry, more particularly manufacture of building components and products intended for protection from ionizing radiations. SUBSTANCE: described is composition comprising sulfur, additive, filler and aggregate. Aggregate is lead shot with particle size of 3-4 mm, and filler is paraffin. Ratios of components are as follows, wt %: sulfur, 7.55-9.5; paraffin, 0.45-0.5; filler resulting from optical glass production waste with specific surface of 2000-2200 sqcm/g 14-17; lead shot aggregate with particle diameter of 3-4 mm, the balance. Products have average density of 6690-7230 kg/cubic m. Water absorption is 0.15-0.18 % for 24 h. EFFECT: increased average density and lower water absorption of the material. 1 tbl
