Abstract
A foamed composition comprising about 100 parts by weight of a hydraulic substance, about 25 to less than about 70 parts by weight water and about 0.01 to about 10 parts by weight of a polymeric foam stabilizer having a weight average molecular weight from about 1,000 to about 20,000 and comprising a homopolymer or copolymer of C.sub.1 -C.sub.12 alkyl carboxylic acids.
Claims7
A foamed composition consisting essentially of from about 25 to less than about 70 parts by weight water, about 100 parts by weight hydraulic substance and about 0.01 to about 10 parts by weight of a polymeric foam stabilizer having a weight average molecular weight from about 1,000 to about 20,000 and comprising a homopolymer or copolymer of C1-C12 ethylenically unsaturated carboxylic acid monomers and salts thereof;
- wherein said composition is prepared by uniformly mixing:
- a) a homogeneously foamed mixture comprising about 25 to less than about 70 parts by weight water and from about 0.01 to about 5 parts by weight of said polymeric stabilizer, and b) a homogeneous slurry comprising about 25 to less than about 70 parts by weight water, about 100 parts by weight of said hydraulic substance, and from about 0.01 to about 5 parts by weight of said polymeric foam stabilizer.
