DRY ADHESIVE CEMENT-BASED MIXTURE Russian patent published in 2016 - IPC C04B28/04 C04B24/16 C04B111/20 

FIELD: construction.

SUBSTANCE: invention relates to dry adhesive cement-based mixture used as tile glue to perform facing work of outer fronts and internal walls of buildings with ceramic tiles. Mixture contains Portland cement, quartz sand, a plasticizer, polymer and a mineral additive and additionally contains as mineral additive synthesized aluminosilicates obtained by sedimentation from liquid glass with silica modulus 2.8 introduction of 15 % solution of technical aluminium sulphate Al₂(SO₄)₃ with subsequent washing with distilled water of obtained sediment and drying at temperature t = 5±105 °C during 24 hours with subsequent grinding into particles sized 5.208-5.704 µm, as polymer additive-Neolith p 4400, as plasticizer Kratasol LFM in the following proportions, wt%: Portland cement M400 53.07-60.05, silica sand, in fractions, mm: 0.630-0.315 23.54-26.67, 0.315-0.14 5.89-6.67, synthesized aluminosilicates with sizes 5.208-5.704 µm 6.05-15.92, additive Kratasol LFM 0.28-0.79, additive Neolith p 4400 0.28-0.79.

EFFECT: technical result is higher adhesion strength and compression strength, reduced slipping down of tiles.
