Title: Proposed Revision to:
Recommended Practice for Selecting Proportions for Normal and Heavyweight Concrete (ACI 211.1-74) (Revised 1975)
Author(s): ACI Committee 211
Publication: Journal Proceedings
Appears on pages(s): 59-60
Keywords: aggregates; air-entrained concretes; air entrainment; exposure: mix proportioning; workability.
Abstract: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.
