METHOD OF PREPARING COMPOSITION FOR ARRANGEMENT OF SELF-ALIGNING FLOOR BASE Russian patent published in 1995 - IPC

FIELD: building materials. SUBSTANCE: firstly desulfurization product of exhaust foam gases which is dried preliminary at 45-50 C is fed to the drive fit mixer, then plasticizer C-3 is added and components were stirred for 2-3 min. Then anhydrite binder and water were added. Water is fed at the quantity provided the ratio B/T 0.2-0.25. Finally, components were stirred for 4-5 min, and prepared mixture is fed to the place of floor base arrangement. Composition has the following components (as dry), wt.-% anhydrite binder 79.0-89.2; product of desulfurization of exhaust gases 9.2-19.0, and superplasticizer on the basis of condensation products of naphthalenesulfoacid with formaldehyde C-3 1.6-2.0. EFFECT: improved method of composition preparing. 2 tbl
