MIXTURE FOR CELLULAR FOAM CONCRETE Russian patent published in 2003 - IPC

FIELD: building materials. SUBSTANCE: invention relates to cellular foam concretes. Mixture for cellular autoclave foam concrete comprises cement, sand, lime, water and the complex foam-forming addition consisting of abietate sodium of the formula C₁₉H₂₉COONa•C₁₅H₂₉COOH,, potassium alkali KOH, hide glue and saturated acid salt in the following ratio of components, wt.-%: abietate sodium, 30.34-33.67; KOH, 6.88-7.64; hide glue, 10.67-11.83; water, 34.11-37.86; saturated acid salt, 9.0-18 in the following ratio of mixture components for cellular foam concrete: cement, 38-42; sand, 28-30; lime, 4.2-4.6; complex foam-forming addition, 0.4-0.7; water, 254.-26.7. Invention provides the development of novel mixture providing preparing autoclave foam concrete with improved physical-mechanical indices, namely, reduced sorption humidity and elevated vapor permeability that provides making comfort conditions in compartments (favorable microclimate). EFFECT: improved and valuable properties of material. 1 tbl
