Standard Test Method for Lightweight Particles in Aggregate

4.1 This test method is used to determine conformance with provisions of Specification C33 pertaining to the amount of lightweight material in fine and coarse aggregates. A heavy liquid with a specific gravity of 2.0 is used to separate particles which may be classified as coal or lignite. Heavier liquids are to be used to check the percentages of other lightweight particles such as chert and ...

Test for Undesirable Lightweight Material - 14070_290

Soft, laminated pieces of aggregate, such as chert or shale, are harmful to concrete. Coal and lignite, also, are harmful and are distinguished from the lightweight materials by the brownish black or black color of the particles. Visual examination of the coarse aggregate will often show these minerals.
