Abstract:
This subcommittee report is intended as a supplement to AC1 Standard "Recommended Practice for Selecting Proportions for Concrete (AC1 613-54)" and describes a procedure for proportioning structural grade concrete containing lightweight aggregates. This procedure does not require the use of values for specific gravity or absorption of the aggregates but utilizes a "specific gravity factor." Use of this factor is illustrated and examples are included for proportioning both air-entrained and non-air-entrained mixes.
