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. |
