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

Test Method Title

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

Reference Number

ASTM C127

Material

Aggregate

Test Property

Specific Gravity

Description of Test

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