Abstract: An admixture composition for inclusion into concrete or other cementitious systems and mixtures includes at least one sealing agent, at least one dispersant agent, and optionally, at least one accelerator agent. The admixture composition allows for the production of concrete and other cementitious products with integral sealing agents.

Abstract: Compositions and methods for coloring concrete and other cementitious systems having improved durability and retention of the colorant when integrally or surface shake applied to any concrete or other cementitious system. The compositions and methods include two phases of high grade dispersion in a combination of particulate polymers selected from particulated polymers, blends of polymers from styrene based polymers and copolymers, acrylic based polymers and copolymers, latex, poly vinyl acetates, polyepoxides, polyurethanes, and any of the family of liquid rubbers, including neoprene, butadiene, water based silanes, silicones, siloxanes, silicates, and any mixture and/or combination of the above. The compositions and methods include organic or oxide colorants.

Abstract: A composition for coloring concrete and methods for making the composition is provided, which includes a hydrophobic efflorescence control agent selected from the group consisting of calcium stearates, zinc stearates, sodium stearates, butyl stearate, stearic acid derivatives, stearic acid salts, and a mixture thereof, a particulated polymer selected from the group consisting of styrene-based polymers and copolymers, acrylic-based polymers and copolymers, polyvinyl acetates, polyepoxides, polyurethanes, butadiene rubbers, and a mixture thereof; and a colorant, wherein the composition improves the durability of the concrete while enhancing the durability and retention of said colorant.

Abstract: An additive for, a method of adding thereof to uncured mixes for and resulting cured cement-type concreations such as cured embodiments of concrete, marcadam, and roof-top shingles each exhibiting improved heat and freeze-thaw durability resulting from reduced efflorescence and stability against sun ultraviolet light exposure.

Abstract: This invention relates to modifying the surface of particles for improved dispersion characteristics in aqueous, solvent, resinous, polymeric, cementitious or the like application systems. In particular, this invention relates to a pigment or filler particle whose surface is coated with at least one electric charge modifying agent and at least one dispersion promoting agent, which has improved dispersibility, coloring, handling, and other processing properties in application systems. The electric charge modifying agent may be selected from the group of Mg, Ca, Ba, Sr, Ti, V, Zr, Cr, Mn, Fe, Co, Ni, Cu, Zn, and Al. The dispersion promoting agent may be selected from the group of stearates, acetates, alkylphenols, cellulosics, waxes, lignins, polyacrylics, polyepoxies, polyurethanes, polyethylenes, polystyrenes and polypropylenes, and polymers having functional groups of alcohols, glycols, aldehydes, amides and carboxylic acids. Iron oxide is the preferred pigment particle.
