Standard Specification for Air-Entraining Admixtures for Concrete

ABSTRACT
This specification covers materials proposed for use as air-entraining admixtures to be added to concrete mixtures in the field. The air-entraining admixture shall conform to the requirements such as initial and final time of setting, compressive strength, flexural strength, and length change (maximum shrinkage). Samples shall either be a grab sample (one obtained in a single operation) or a composite sample (one obtained by combining three or more grab samples). For the purpose of this specification, it is recognized that samples shall be taken for quality tests and uniformity tests.
SCOPE
1.1 This specification covers materials proposed for use as air-entraining admixtures to be added to concrete mixtures in the field.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 air-entraining admixture, n—for the purpose of this specification, a material that is used as an ingredient of concrete,
added to the batch immediately before or during its mixing, for the purpose of entraining air.
4. General Requirements
4.1 At the request of the purchaser, the manufacturer shall state in writing that the air-entraining admixture supplied for use in
the work is essentially identical in concentration, composition, and performance to the air-entraining admixture tested under this
specification.
NOTE 1—It is recommended that, whenever practicable, tests with the air-entraining admixture be made using all of the ingredients of the concrete
proposed for the specific work, because the effect produced by the air-entraining admixture may vary with the properties of the other ingredients of the
concrete.
4.2 Requirements for establishing compositional or chemical equivalence of a subsequent lot relative to a previous lot that was
subjected to quality tests and found to comply with the requirements of 5.1 shall be determined if agreed upon by the purchaser
and the manufacturer. At the request of the purchaser, the manufacturer shall recommend appropriate test procedures, such as
infrared spectrophotometry (I.R.), pH value and solids content, for establishing the equivalence of materials from different lots or
different portions of the same lot.
NOTE 2—Ultraviolet light absorption (UV) of solutions and infrared spectroscopy of dried residues have been found to be valuable for these purposes.
The specific procedures to be employed and the criteria to establish equivalence should be stipulated with due regard to the composition and properties
of the sample.
4.3 At the request of the purchaser, the manufacturer shall state in writing the chloride content of the air-entraining admixture
and whether or not chloride was added during its manufacture.
NOTE 3—Admixtures that contain chlorides may accelerate corrosion of embedded metals.
