    Significance and Use

    3.1 This test method is not widely used. However, it is a convenient procedure for field or plant determination of moisture content of fine aggregate if specific gravity values are known and if drying facilities are not available. It can be used to adjust the aggregate mass for moisture content and to determine surface moisture contribution to mixing water in portland cement concrete.

    3.2 The accuracy of the test method depends upon accurate information on the bulk specific gravity of the material in a saturated surface-dry condition.

    1. Scope

    1.1 This test method covers field determination of the amount of surface moisture in fine aggregate by displacement in water.

    1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
