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

Volume: 74

Issue: 2

Appears on pages(s): 59-60

Keywords: aggregates; air-entrained concretes; air entrainment; exposure: mix proportioning; workability.

Date: 2/1/1977

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.
