FIRE-RESISTANT VISCOUS-FLOW COMPOSITION Russian patent published in 2005 - IPC

FIELD: manufacture of building materials.

SUBSTANCE: invention relates to fiber-reinforced easily moving and fluid compositions that can be used in building material industry as binder when manufacturing nonflammable heat-insulation and other building materials and which can play part as plugging material to close cracks, including those with elevated surface temperature. Composition contains 28-56% liquid glass, 34-65% aluminosilicate waste, 5.9-9.8% iron-containing wastes, and 0.1-0.2% finely dispersed mineral additive, wherein said aluminosilicate waste is granulated blast furnace slag or slag beads; said iron-containing wastes are those from blast-furnace production imparting alkalinity to a water extract and having specific surface 100-150 m²/kg, blast furnace dust, or ore agglomeration waste; and said finely dispersed mineral additive are wood ashes.

EFFECT: improved compaction strength, water resistance, and rheological properties without loss in fire resistance.
