Standard Specification for Chemical Admixtures for Use in Producing Flowing Concrete (Withdrawn 2022)

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. (A) The values in the table include allowance for normal variation in the test results. The object of the 90 % strength requirements is to require a level of performance comparable to that of the reference concrete.(B) Alternative Requirements—Percent of reference limit applies when length change of reference is 0.030 % or greater; increase over reference limit applies when length change of reference is less than 0.030 %.(C) The requirement is applicable only when the admixture is to be used in air-entrained concrete which may be exposed to freezing and thawing while wet.  
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 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 th...
