    Abstract

    Current methods of determining the specific gravity, moisture content, and absorption of concrete aggregates (ASTM Test Method for Specific Gravity and Absorption of Coarse Aggregate [C 127], ASTM Test Method for Specific Gravity and Absorption of Fine Aggregate [C 128], and ASTM Test Method for Total Moisture Content of Aggregate by Drying [C 566]) are slow and dependent upon subjective “end-point” determinations as well as requiring elaborate and cumbersome equipment. Presented here is a method using simple equipment, the siphon can, to accomplish all three tests. This technique has an objective “end-point” and statistical error of measurement one-quarter that of ASTM C 127 or C 128. Derivation of formulae and method of application are discussed. The use of this technique in routine concrete production can result in large savings to concrete producers.
