Standard Test Method for Lightweight Particles in Aggregate
Also Known As:
The ASTM C123/C123M-14 standard is titled "Standard Test Method for Lightweight Particles in Aggregate". This test method is used to determine the presence and percentage of lightweight materials in fine and coarse aggregates. The test involves using a heavy liquid with a specific gravity of 2.0 to separate particles that may be classified as coal or lignite. For other lightweight particles such as chert and shale with a specific gravity less than 2.40, heavier liquids are used for checking their percentages.
The standard also mentions that this test method is useful for identifying porous aggregate particles in research activities or in petrographic analyses. The test is conducted by performing a sink-float separation of the aggregate in a heavy liquid with suitable specific gravity. The standard also includes notes and footnotes that provide explanatory material but should not be considered as requirements of the standard.
