An exemplary composition for enhancing water repellency in cementitious material comprises a hydrophobic material solute that is dissolved in a glycol ether solvent. Thus, the composition is provided in the form of a non-aqueous solution or emulsion wherein water is in a noncontinuous phase. The use of such compositions to modify cementitious compositions and the cementitious materials obtained thereby are also described.

Integrally waterproofed concrete

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.
