    (What is a Work Item?)

    Developed by Subcommittee: C09.25 | Committee C09 | Contact Staff Manager



    WK22058

    1. Scope

    1.1 This test method is suitable for laboratory use to determine one or more of the following: 1.1.1 The bond strength of a repair or an overlay material to a specific concrete substrate; 1.1.2 The tensile strength of a repair or overlay material, used in repairs, after the material has been applied to a surface; 1.1.3 The change in bond strength when applying a bonding agent or other bond modifying treatment; and 1.1.4 The tensile strength of the concrete substrate. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
