The Use of the Foam Index Test to Predict AEA Dosage in Concrete Containing Fly Ash: Part I—Evaluation of the State of Practice

CODEN: JAIOAD

Abstract

Foam index tests can be used to predict the air-entraining admixtures dosages for concrete containing fly ash. No industry-accepted foam index test standard exists and widely different methods have been used in research and industry. Four foam index test variants were compared to determine if variations of the test method alter the results or change the decisions one makes on the basis of the test. This is Part I of a three-part series that compares existing foam index methods, identifies factors to which the tests are most sensitive, and proposes detailed guidelines for a standard test method.
