Abstract
Exemplary emulsion admixture for use in hydraulic cement compositions formed by emulsifying an antifoaming agent, surfactant, and a comb polymer having a carbon-containing backbone to which are attached cement-anchoring members and oxyalkylene groups. A method of making a stable emulsion admixture comprising the comb polymer, as well as a hydraulic cement composition comprising the admixture, are also described.
