Aggregate Gradation: Testing Tips and Tricks

Wet it Down. Wet-washing aggregate specimens according to ASTM C117 is a process that removes materials finer than 75µm (No. 200) from the sample material. The fraction of the sample removed in this process is often referred to as P200, as in the fraction …

Gradation of Aggregates

The coarser the aggregate, the higher the FM. For fine aggregate used in concrete, the FM generally ranges from 2.3 to 3.1 as called for in ASTM C 33, but in some cases, fine sands are used with a FM less than 2.0 and in other cases, a coarser fine aggregate with an FM higher that 3.1.
