Abstract: A sealer composition for a cementitious substrate, a cementitious structure sealed with the sealer composition, and a method of sealing a steel reinforced cementitious structure with the sealer composition. The sealer composition includes a substantially non- aqueous blend of a first silane, a second silane having a higher molecular weight than the first silane, and a corrosion inhibitor. The corrosion inhibitor is soluble in silane, soluble in solvent-diluted silane, and at least partially soluble in water. The cementitious structure includes a cementitious substrate and the sealer applied to the surface of the substrate and at least partially penetrating into the substrate. The method of sealing a steel reinforced cementitious structure from intrusion of corrosion-causing agents includes applying the sealer to the surface of a steel reinforced cementitious substrate and permitting the sealer composition to penetrate into the substrate to seal the substrate.

Abstract: An admixture formulation of at least one polycarboxylate dispersant and at least one naphthalene dispersant is provided. When the polycarboxylate dispersant and the naphthalene dispersant of the admixture formulation are combined at various ratios the admixture formulation reduces the tendency for bleed and segregation in cementitious mixtures without increasing water demand, retarding setting, increasing water sensitivity, promoting high viscosity, or reducing flow retention.

Abstract: A method of making a grout composition which reduces the amount of bleed water from grout used in bonded post-tensioned concrete applications is provided. The method includes forming the grout composition by combining copolymers with other materials into a hydraulic cementitious composition. The copolymers are formed from structural components a) to c) and optionally d) which are mono-unsaturated compounds, with a generally linear macromolecular structure. By reducing the amount of bleed water in bonded post-tensioned concrete applications the grout composition provides protection from corrosion for the steel members, including stranded tendons and solid bars. The reduction in the amount of bleed water is achieved without significantly increasing the viscosity of the grout mixture thereby allowing good pumpability, placement, and maintenance of other properties such as resistance to volume change, long working time and acceptable strength development.

Abstract: A tracer material having an identifiable property associated with a particular type product and/or a particular manufacturer is blended with dry, powder hydraulic cement-based building materials, which set to a hardened product after admixing with water or another hardening agent, to provide the capability of making a simple analysis of the hardened product to determine the presence or absence of the tracer material and thereby positively identify whether the building material used to produce the hardened product was a particular type and/or supplied by a particular manufacturer. The building material can be analyzed in the dry powder form prior to use to make the same type determination.
