The foam index test can be useful for predicting air-entraining admixture (AEA) dosage in concrete or for evaluating AEA interaction with other mixture ingredients. The test is sensitive to several factors including total water content, water-cementitious materials ratio, ash-cementitious materials ratio, and others. This study isolates several key factors and examines their influence on foam index test results. Recommendations for a standard test are proposed.
