  • Patent number: 6441054
    Abstract: An exemplary surface active agent admixture composition of the invention comprises (1) a first surface active agent comprising a betaine, an alkyl or aryl or alkylaryl sulfonate, or mixture thereof; and (2) a second surface active agent comprising a nonionic oxyalkylene-containing polymer surfactant. The present invention therefore provides a system for ensuring the presence in a hydratable cementitious composition (when hardened) a sufficient air volume and sufficient air void fineness and consistency. Further exemplary admixture compositions may comprise one or more plasticizers and one or more clay activity-modifying agents. Cementitious compositions and methods for modifying cementitious compositions, which incorporate the above-mentioned surface active agent combination, are also described. The invention provides the ability to adjust and stabilize air void systems in hydratable cementitious compositions, while allowing conventional air entraining agent (AEA) dosage practices to be followed.

  • Patent number: 6358309
    Abstract: A wall repair compound useful for filling and repairing cracks, holes, and other imperfections in a wall surface includes a conventional filler material, a conventional binder material, and a dust reducing additive which reduces the quantity of airborne dust particles generated when sanding the hardened joint compound. Airborne dust reducing additives include oils, surfactants, solvents, waxes, and other petroleum derivatives. The additive can be added to conventional ready-mixed joint compounds and to setting type joint compounds. The method of reducing the quantity of airborne dust generated when sanding a fully hardened joint compound includes mixing a sufficient quantity of the dust reducing additive with the joint compound prior to when the joint compound has been applied to the wall.

  • Publication number: 20020005149
    Abstract: Admixture or additive which provides water-repellency and flexural bond strength improvement in mortar, concrete, or cement, and particularly in masonry mortars. An exemplary admixture composition includes: (a) at least one C8-C30 fatty acid or a derivative thereof, such as a salt, ester, or triglyceride; and (b) a flexural bond strength enhancing material comprising a polymer having a backbone to which are attached carboxyl cement anchoring groups and oxyalkylene groups attached by linkages selected from the group consisting of an amide, an imide, and an ester. A preferred additive optionally includes an air entraining admixture for improving workability of a masonry mortar into which the fatty acid or derivative and the flexural bond strength enhancing material are added. A cementitious composition and method for enhancing water-repellency and flexural bond strength in a masonry mortar are also disclosed.

  • Patent number: 6277191
    Abstract: 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.
