ASTM C1017/C1017M-13e1 PDF Download

ASTM C1017/C1017M-13e1 is a standard specification that covers the requirements for chemical admixtures used in hydraulic cement concrete mixtures to produce flowing concrete. The specification defines two types of chemical admixtures: Type I (plasticizing) and Type II (plasticizing and retarding). The specification also outlines the tests that the chemical admixtures must undergo, including tests for time of setting, increase in slump, compressive strength, flexural strength, length change after drying, and relative durability factor.

The standard provides guidelines for testing the chemical admixtures with reference concreting materials or with specific concrete-making materials proposed for a particular project. It also allows for three levels of testing: Level 1, which involves initial approval and proof of compliance with the performance requirements; Level 2, which involves limited retesting to demonstrate continued conformity; and Level 3, which is used for acceptance of a lot or for measuring uniformity within or between lots.

The specification also discusses the importance of uniformity and equivalence in chemical admixtures, and provides requirements for establishing uniformity and equivalence through tests such as infrared analysis, residue by oven drying, and specific gravity. Additionally, the standard includes information on various notes and footnotes that provide explanatory material, but these notes and footnotes are not considered as requirements of the standard.
