Evaluation of the Air Void Analyzer [PDF]

, 2013
Abstract : The U.S. Army Engineer Research and Development Center (ERDC) conducted an evaluation of the Air Void Analyzer (AVA) to determine the machine s ability to accurately and precisely measure the air void structure of freshly prepared portland cement concrete (PCC). This evaluation consisted of producing multiple batches of PCC in the laboratory
