| 1. Scope | |
|
1.1 This specification covers materials for use as chemical admixtures to be added to hydraulic-cement concrete mixtures in the field for the purpose or purposes indicated for the eight types as follows: 1.1.1 Type A—Water-reducing admixtures, 1.1.2 Type B—Retarding admixtures, 1.1.3 Type C—Accelerating admixtures, 1.1.4 Type D—Water-reducing and retarding admixtures, 1.1.5 Type E—Water-reducing and accelerating admixtures, 1.1.6 Type F—Water-reducing, high range admixtures, 1.1.7 Type G—Water-reducing, high range, and retarding admixtures, and 1.1.8 Type S—Specific performance admixtures. 1.2 This specification stipulates tests of an admixture with suitable concreting materials as described in 11.1-11.3 or with cement, pozzolan, aggregates, and an air-entraining admixture proposed for specific work (1.3 This specification provides for three levels of testing. 1.3.1 Level 1—During the initial approval stage, proof of compliance with the performance requirements defined in 1.3.2 Level 2—Limited retesting is described in 5.2, 5.2.1 and 5.2.2. Proof of compliance with the requirements of 1.3.3 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 Section 1.4 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 the standard. 1.5 The text of this standard 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. 1.6 The following precautionary caveat pertains only to the test method sections, Sections | |
