Aggregate Gradation: Testing Tips and Tricks - .

Fine aggregate samples or samples of unprocessed mixed-size material from natural deposits sometimes contain a high proportion of fines. The extra fines make handling, sample dividing, and sieving difficult, and needlessly generate a lot of dust. 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 ...

Fine Aggregate Specific Gravity - Pavement Interactive

Overview. The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the coarse aggregate specific gravity test.. Figure 1: Fine aggregate specific gravity sample and pycnometer.
