Coarse Aggregates in Construction
The Fine Aggregate Test (ASTM C128 and AASHTO T 84) is a comparison of sample masses in oven-dry, saturated surface-dry (SSD), and immersed conditions. This test method offers alternate procedures to determine specific gravity. Either a volumetric flask or a simple pycnometer can be used for the gravimetric procedure. For the volumetric procedure, a special Le Chatelier flask is needed.

For example coarse aggregate has a standard grading requirement for each different size from #1 to #8. A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate is a nominal size of 3/8 to 0.094 inch. More specifically, a #57 aggregate is the combination of #5 and #7 aggregates ranging from 1 to 0.19 inch.
