Significance and Use

These test methods are used to develop data for comparison with the requirements of Specification C 1438 . Standardized procedures are used to compare the properties of specimens made from test mixtures of polymer-modified concrete or mortar with the properties of specimens made from reference mixtures. These test methods are not intended to simulate job conditions.

1. Scope

1.1 These test methods provide a means of determining the effect of adding polymer modifiers to reference concrete or mortar.

1.2 Most sections of ASTM test methods and practices for hydraulic cement mortar and concrete apply to the preparation and testing of specimens made with polymer-modifiers. However, there are some exceptions, most notably curing, that need special procedures in order to develop the properties inherent with polymer-modification. These test methods cover these exceptions.

1.3 For testing polymer-modified mortar and concrete specimens, the procedures in this standard supersede those in the referenced ASTM test methods and practices. These test methods are not applicable to dry, packaged mortar and concrete.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 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. ( Warning Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. )
