ASTM C70 – Standard Test Method for Surface Moisture in Fine Aggregate
Description:
Significance and Use
4.1 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.
4.2 The accuracy of the test method depends upon accurate information on the bulk specific gravity of the material in a saturated surface-dry condition.
Scope
1.1 This test method covers field determination of the amount of surface moisture in fine aggregate by displacement in water.
1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
