    This specification covers the performance criteria for latex and powder polymer modifiers for improving the adhesion and reducing permeability of hydraulic cement concrete and mortar. The polymer modifiers are classified either for general use or for use in areas not exposed to moisture and should be able to produce test mortar or test concrete that conforms to the specified requirements.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers performance criteria for latex and powder polymers when used as modifiers in hydraulic cement concrete and mortar to improve adhesion and reduce permeability (see Note 1).

    Note 1: For further information concerning theory, benefits, limitations, and applications of polymer-modified hydraulic cementitious mixtures, refer to ACI 548.3R-09.2

    1.2 The performance criteria are based on certain property changes that are achieved by use of the polymer modifier when compared to reference concrete or mortar (Test Methods C1439).

    1.3 Prepackaged, proprietary mortar products are not included in this specification. Also, this specification covers only those materials contained in the reference or test mixtures listed in Test Methods C1439.

    1.4 The values stated in SI units are to be regarded as standard.

    1.5 The following precautionary statement pertains only to the test method portion, Section 10, of this specification: 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.6 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.
