    (What is a Work Item?)

    WK23938

    1. Scope

    1.1 This specification covers materials for use as shrinkage-reducing admixtures (SRAs) for concrete. 1.2 Results of the tests conducted to meet this specification are not to be used to rank the expected field performance of various SRAs. 1.3 The values stated in either SI units or inch-pound shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other without combining values in any way. 1.4 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

    Shrinkage-reducing admixtures are being used today without a standard to guide users on their use.
