Keywords: aggregates; air-entrained concretes; air entrainment; exposure: mix proportioning; workability.
The objective of the proposed revision is to allow some flexibility in mix propor-tioning when air-entrained concrete is specified. To this effect three levels of air content are given for each chosen workablity and aggregate size in function of the severity of exposure.
