    摘要: Substantially hydrated cementitious particulates useful for delivering admixtures and additives into adhesives, coatings, paints, and other matrix compositions such as cement, concrete, masonry, mortar, fireproofing, shotcrete, and others. Preferred embodiments include intermixing at least one admixture, water, and hydratable cementitious binder to provide a substantially hydrated hardened mass and comminuting the hardened mass into particulates. Alternatively, or in addition, one or more admixtures may be coated onto the external surface area of the particulates, which are microscopically granulosic, to provide accurate and high level loading.

    摘要: The present invention relates to a method and air entraining admixtures (AEAs) for achieving satisfactory levels of air entrainment in a hydraulic cementitious composition, such as concrete or mortar, in which an oxyalkylene shrinkage reduction admixture (SRA) is used with, or to be used in combination with, a water soluble salt, such as a calcium salt. Addition of exemplary polyoxyalkylene copolymers, preferably nonionic and substantially di-block in structure, and preferably having a molecular weight of at least 1,000 and more preferably at least 2,000, are described for controlling air entrainment. Increased air entrainment effect is fiber realized when such polymers are used with conventional AEAs, such as tall oils and vinsol resin.
