Abstract
A method of controlling the level of entrained air in hydraulic cement compositions is disclosed comprising the sequential steps of preparing a hydraulic cement composition in the form of an aqueous slurry containing an air entraining plasticizer and a defoamer, and increasing the air content of the composition by adding to said composition an air entraining agent. This method prevents undesired air entrainment, while allowing controlled amounts of air to be entrained if desired for freeze/thaw durability.
