ASTM C127 Standard Test Method for Density, Relative Density (Specific Gravity), and Absorption of Coarse Aggregate -- eLearning Course
About the Course
This course covers the determination of relative density (specific gravity) and the absorption of coarse aggregates. The relative density (specific gravity), a dimensionless quantity, is expressed as oven-dry (OD), saturated-surface-dry (SSD), or as apparent relative density (apparent specific gravity). The OD relative density is determined after drying the aggregate. The SSD relative density and absorption are determined after soaking the aggregate in water for a prescribed duration.
The course takes approximately 1 hour to complete and includes instructional video content, interactive knowledge checks, and a self-grading quiz. Downloadable resources include a pdf of the standard.
Learning Outcomes
By the end of this course you will be able to:
- Describe the requirements for obtaining a sample, including what to do with materials finer than the 4.75-mm (No. 4) sieve or larger than the 37.5-mm (11/2-in.) sieve.
- Recall how to obtain relative density (specific gravity) and absorption values by the outlined sequence of drying and soaking outlined in the procedure.
Audience
Anyone who runs the C127 test method or who needs an understanding of the test method and how it is properly run.
