Abstract:
This article discusses air-entrained concrete, advantages of air entrainment, the effects of supplementary cementitious materials (SCMs) on the air-entraining admixture (AEA) dosage, and the effects of production and construction variables on air content. It explains parameters such as total air content, air-void size and distribution, spacing factor, and specific surface, and summarizes testing methods and relevant specifications, as well as alternatives to AEA.
