ASTM C1017/C1017M − 13 1 Standard Specification for Chemical Admixtures for Use in Producing Flowing Concrete

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.
