1.1 This specification covers performance criteria for latexes and redispersible powders when used as modifiers in hydraulic cement concretes and mortars 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 ACE 548.3R-95.
1.2 The performance criteria are based on certain property changes that are achieved by use of the polymer modifier compared with reference concrete or mortar (Test Methods C 1439).
1.3 Prepackaged, proprietary mortar products are not included in this specification. Also, this specification does not cover cementitious mixtures modified with organic polymer latexes and powders.
1.4 The values stated in SI unites 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 and health practices and determine the applicability of regulatory limitations prior to use.
