ASTM C117 - 17 Standard Test Method for Materials

1.1 This test method covers the determination of the amount of material finer than a 75-μm (No. 200) sieve in aggregate by washing. Clay particles and other aggregate particles that are dispersed by the wash water, as well as water-soluble materials, will be removed from the aggregate during the test.How to Expose the Aggregate - The Concrete Network,Using a surface retarderToday, most contractors expose aggregate by spraying a chemical surface retarder onto the slab surface immediately after placing and finishing. This delays the set and gives them the flexibility to remove the cement paste up to a day or so later, either by scrubbing or pressure washing.Washing of Aggregates - Influence on Aggregate,reference aggregate in the washing experiments in this work. 2.2 Methods Washing procedure The aggregates were washed in the laboratory by using a bucket and stirring machine.
