Test Method Title

Standard Test Method for Density, Relative Density (Specific Gravity), and Absorption of Fine Aggregate

Reference Number

ASTM C128

Material

Aggregate

Test Property

Specific Gravity Relative Density Absorption

Description of Test

A sample of aggregate is immersed in water for 24 +/- 4 hr to essentially fill the pores. It is then removed from the water, the water is dried from the surface of the particles, and the mass determined. Subsequently, the sample (or a portion of it) is placed in a graduated container and the volume of the sample is determined by the gravimetric or volumetric method. Finally, the sample is oven-dried and the mass determined again. Using the mass values thus obtained and formulas in this test method, it is possible to calculate density, relative density (specific gravity), and absorption.
