ASTM C1017/C1017M-13

Standard Specification for Chemical Admixtures for Use in Producing Flowing Concrete

ABSTRACT
This specification covers chemical admixtures to be added to hydraulic cement concrete mixtures for use in producing flowing concrete. The two types of chemical admixtures are: Type I—plasticizing; and Type II—plasticizing and retarding. Tests of the chemical admixtures with reference concreting materials or with concrete-making materials proposed for specific work are specified. Three levels of testing are discussed: Level 1, Level 2, and Level 3. Type of admixtures shall conform to the physical requirements: time of setting, increase in slump, compressive strength, flexural strength, length of change after days of drying, and relative durability factor. Uniformity and equivalence shall be established by the following requirements: infrared analysis, residue by oven drying (liquid and nonliquid admixtures), and specific gravity (liquid admixtures). Tests for quality, uniformity, and equivalence shall be made. Samples of freshly mixed concrete shall be tested according to slump, air content, time of setting, and water content and unit weight. Hardened concrete shall be tested according to the following: compressive strength, flexural strength, resistance to freezing and thawing, and length change.
SCOPE
1.1 This specification covers two types of chemical admixtures to be added to hydraulic cement concrete mixtures for the purpose of producing flowing concrete. The types are as follows:  
1.1.1 Type I—Plasticizing, and  
1.1.2 Type II—Plasticizing and retarding.  
1.2 This specification stipulates tests of a chemical admixture with reference concreting materials or with concrete-making materials proposed for specific work. Unless otherwise specified by the purchaser, the tests shall be made using reference concreting materials.  
1.3 If a chemical admixture has been tested and found to comply with the provisions of this specification using reference materials, and is being considered for use with other materials for specific work, additional tests for such use are allowed if agreed upon between the purchaser and the supplier and are allowed to consist of a portion of the tests described herein.  
1.4 This specification provides for three levels of testing.  
1.4.1 Level 1—During the initial approval stage, proof of compliance with the performance requirements defined in Table 1 demonstrates that the admixture meets the requirements of this specification. Uniformity and equivalence tests of the section on Lot Uniformity and Equivalence shall be carried out to provide results against which later comparisons can be made.TABLE 1 Physical RequirementsA

1. Scope*
1.1 This specification covers two types of chemical admixtures to be added to hydraulic cement concrete mixtures for the
purpose of producing flowing concrete. The types are as follows:
1.1.1 Type I—Plasticizing, and
1.1.2 Type II—Plasticizing and retarding.
1.2 This specification stipulates tests of a chemical admixture with reference concreting materials or with concrete-making
materials proposed for specific work. Unless otherwise specified by the purchaser, the tests shall be made using reference
concreting materials.
1.3 If a chemical admixture has been tested and found to comply with the provisions of this specification using reference
materials, and is being considered for use with other materials for specific work, additional tests for such use are allowed if agreed
upon between the purchaser and the supplier and are allowed to consist of a portion of the tests described herein.
1.4 This specification provides for three levels of testing.
1.4.1 Level 1—During the initial approval stage, proof of compliance with the performance requirements defined in Table 1
demonstrates that the admixture meets the requirements of this specification. Uniformity and equivalence tests of the section on
Lot Uniformity and Equivalence shall be carried out to provide results against which later comparisons can be made.
1.4.2 Level 2—Limited retesting described in the section relating to general requirements may be requested at intervals by the
purchaser. Proof of compliance with the requirements of Table 1 demonstrates continued conformity of the admixture with the
requirements of the specification.
1.4.3 Level 3—For acceptance of a lot or for measuring uniformity within or between lots, when specified by the purchaser, the
uniformity and equivalence tests of the section on Lot Uniformity and Equivalence shall be used.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values in inch-pound
units shown in parentheses are provided for information purposes stated in each system may not be exact equivalents; therefore,
each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with
the standard. Some values have only SI units because the inch-pound equivalents are not used in practice.
NOTE 1—Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information
only and does not represent a different standard sieve size.only.
NOTE 2—It is recommended that, whenever practicable, tests be made using the concrete-making materials (cement, pozzolan, slag, aggregates,
air-entraining admixture), the mixture proportions, and the batching sequence and other physical conditions proposed for the specific work. The specific
effects produced by chemical admixtures may vary with the properties and proportions of the other ingredients of the concrete.
NOTE 3—Temperature has a pronounced effect on time of setting of concrete. This may be exaggerated by the use of admixture Types I and II. If
concrete temperatures to be expected on a particular job differ significantly from the conditions set forth in this specification, further testing may be
desirable.
NOTE 4—An unusually rapid loss of workability with time, sometimes termed “slump loss”, can be experienced with these admixtures. The rate of
slump loss will vary with the particular concreting materials and proportions, mixing equipment and procedures, and temperatures experienced on any
particular job. At elevated temperatures, the slump may be retained for a longer period if a Type II admixture is used.
NOTE 5—Admixtures that contain relatively large amounts of chloride may accelerate corrosion of prestressing steel. Compliance with the requirements
of this specification does not constitute assurance of acceptability of the admixture for use in prestressed concrete (see ACI 318).
