American Concrete Institute

The bulletin takes a non-technical approach to a complex topic. In addition to explaining the various ways admixtures can improve concrete performance, it introduces the functions and applications of the following admixture types:

• Air entraining
• Water reducing and set controlling
• Corrosion inhibiting
• Shrinkage reducing
• Admixtures for controlling alkali-silica reactivity
• Admixtures for underwater concreting

The publication also provides information about the dispensing systems ready-mix plants use to accurately measure and inject liquid admixtures into concrete mixtures and the recommended injection sequence for the various classes of admixtures. A list of relevant ASTM standards and an admixture glossary are included for quick reference.

The cost of the 12-page bulletin is $14.00 for ACI members (nonmember price is $22.50). For more information or to order, call (248) 848-3800 or visit www.concrete.org.
