【国外标准】 Standard Specification for Latex Agents for Bonding Fresh To Hardened Concrete

This specification covers the requirements for latex bonding agents suitable for use in brushes, brooms, or sprays. The bonding agents are intended for use in bonding fresh concrete to hardened concrete such as in interior surfaces, floors, roadways, bridge decks, ramps, runways, walks, and curbs. Each material should comply with the specified bond strength requirement for either of the two types of latex.1.1 This specification covers latex bonding agents, suitable for brush, broom, or spray application, to bond fresh concrete to hardened concrete.1.2 These latex bonding agents are intended for bonding new concrete to old concrete such as interior surfaces, floors, roadways, bridge decks, ramps, runways, walks, and curbs.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.4 The text of this specification refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
