Aggregate Gradation: Testing Tips and Tricks - Gilson Co.

In this case, washing is a matter of convenience and housekeeping. Coarse aggregate samples may not require a P200 determination at all, but it still may be helpful to wash them. On the other hand, an accurate P200 value may be an important focus of the requested gradation tests, especially with fine aggregate specimens.

In order to ensure the aggregate performs as intended for the specific use, a variety of tests must be performed on the aggregate. One such test is determining materials finer than No. 200 (75 µm) sieve in mineral aggregates by washing. Fine materials such as clay particles or water soluble particles removed by washing,

The real issue with trying to use washing equipment to sort and classify has to do with nature: You’ll seldom find the ideal gradation in naturally occurring deposits. If part of quality control involves getting the aggregate to an ideal gradation, then you’re forced to rely more on additional processes such as screening, crushing, and ...

an aggregate by percent of weight. Gradation is determined by filtering an aggregate through successively smaller sieves and measuring the weight retained on each sieve. Fine content (-#200 sieve or smaller than ~0.003 inches) is determined by washing the aggregate to separate this fine material from the larger pieces.

Sep 10, 2015  Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material: Generally above 3/8 in. (sometimes split at 1/4 in. or #4 mesh). In the washing process it usually is desired to remove foreign, objectionable material, including fine particles. Fine aggregate: From 3/8 in. and smaller.
