摘要 |
FIELD: manufacture of building materials. SUBSTANCE: concrete mixture for manufacturing floor contains, wt %: Portland cement 15-20, expanding additive 1.2-2.0, crushed rock fraction 5-10 mm - 42-49, sand (2.0-2.2 mm) 25-29, and water - the balance. Expanding additive contains 40-50 wt % of alumina-containing component with alumina content 20% and 50-60 wt % of sulfate-containing component with at least 35%. sulfur trioxide content. Concrete is characterized by axial elongation value 1.1- 1.3 that of estimated value and water permeability 8 to 20 atm. EFFECT: improved characteristics. 1 tbl
