Filed:

Jul 25, 2003

Appl. No.:

10/626971

Inventors:

Frederick R. Goodwin - Solon OH, US

Assignee:

Construction Research & Technology GmbH - Trostberg

International Classification:

F16L 9/147

US Classification:

138176, 5274214, 5274216, 522231, 427219, 427403, 428378, 428404

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.

International Classification:

C04B 24/04

US Classification:

106724, 106727, 106728, 106823, 524 5

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.

International Classification:

C04B 700

US Classification:

106638

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.
