Abstract

Several problems are identified in regard to air-entrained concrete, which include the accuracy of the pressure air meter (ASTM C 231), the accumulation of air voids at the coarse aggregate surface, excessive loss of air volume in transit or in pumping, and the need for greater precision and detail in specification requirements for air-entrained concrete. Data are presented from four recent construction projects from a wide geographical range in the United States.
