Abstract:
This sixth report of ACI Committee 212, now named "Chemical Admixtures for Concrete," updates the previous reports of 1944, 1954, 1963, 1971, and 1981. Admixtures discussed herein are those known as chemical admixtures; finely divided mineral admixtures have been transferred to ACI Committee 226. Admixtures are classified into five groups: air-entraining, accelerating, water-reducing and set-controlling, admixtures for flowing concrete, and miscellaneous. "Preparation and batching," which had a separate chapter in the 1981 Report, is included in Chapter 1. Chapter 5, "Admixtures for flowing concrete," is new, representing technology that has matured since 1981. Those admixtures possessing properties identifiable with more than one group are discussed with the group that describes its most important effect on concrete.
