Summary:Well cementing compositions include an aqueous fluid, portland cement, and an air entrainment suppressing agent. The air entrainment suppressing agent includes a blend of a silicone and polypropylene glycol, or a silicone that is functionalized with ether groups. Methods for preparing well cementing compositions comprise adding the air entrainment suppressing agent to the aqueous fluid, and combining the mixing fluid to a solid blend comprising portland cement and hydrophobic particles in a continuous process.
