WATER-PROOF COAT

摘要

FIELD: manufacture of building materials; water-proof coats; water-proof shields for fields of burial of waste; sludge barns and pits. ^ SUBSTANCE: proposed water-proof coat contains oil production waste - asphalt-resin-paraffin deposits and polymer in form of poly-formaldehyde at the following ratio of components, mass-%: asphalt-resin-paraffin deposit, 60-80; waste poly-formaldehyde,20-40. ^ EFFECT: enhanced homogeneity of fine-grained compound; enhanced strength; low water absorption and seepage coefficient; improved deformation properties; utilization of waste. ^ 1 tbl
