RESIN-CEMENT MIX FOR MAKING FLOORS Russian patent published in 1997 - IPC

FIELD: preparation or mortar mixes, more particularly resin-cement mixes for making chemically resistant and impermeable mosaic floors in industrial, civic and agricultural buildings. SUBSTANCE: resin-cement mix comprises, wt. -%: Portlant-cement, 22.0-23.0; 5-% phthalate modified polyvinyl acetate slurry, 22.0-23.0; 5-12-mm fraction marble crumb, 32.0-38.0; 19.6- 22.2 0.63-2.5-mm fraction sand with M_c 1.6-2.2, 19.6-22.2; and 0.14-0.315-mm fraction sand with M_c 1.1-1.6, 8.1-12.1; sinoxanolate emulsion in tetraethoxysilane, 0.5-1.5; and water, 7.2-7.8. Water resistance coefficient is not greater than 0.96; oil resistance coefficient is not greater than 0.97; kerosene resistance coefficient is not greater than 0.93; gasoline resistance coefficient is not greater than 0.89. Water absorption of mix up to 30 days is not greater than 4.4%. Linear shrinkage is not greater than 0.42 mm/m. EFFECT: improved properties of the resin- cement mix. 2 tbl
