Abstract
An improved foamed hydraulic composition comprising at least one hydraulic substance, from about 20 to about 130 parts water, and from about 0.01-30 parts of a copolymeric foam stabilizer based on 100 parts hydraulic substance, where the copolymeric foam stabilizer is formed from one or more non-ionic, ethylenically-unsaturated monomers and one or more ionic or ionizable ethylenically-unsaturated monomers containing carboxylic acid.
Claims36
A foamed hydraulic composition consisting essentially of at least one hydraulic substance and from about 25 to about 130 parts by weight water, and from about 0.01 to about 30 parts by weight of a copolymeric foam stabilizer, based on 100 parts hydraulic substance, wherein said copolymeric foam stabilizer is a copolymer formed from
- a) about 0.1% to about 98% by weight of one or more nonionic, ethylenically-unsaturated monomers and
- b) about 2% to about 40% by weight of one or more ionic or ionizable ethylenically-unsaturated monomers, at least one of said monomers containing carboxylic acid.
