17 Aggregate Stability and Size Dlstributlon'

    Aggregate-size distribution is affected strongly by the tillage treat-menus) to which the soil has been subjected and the procedure by which the sample was taken and prepared for sieving. Consequently, by stand-ardizing the sampling procedure, the rotary sieve can be used to obtain good measures of the effects of tillage implements on the aggregate-size distribution, which Chepil (1941) found ...

    Characteristics of Aggregates: Shape, Size & .

    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 simple pycnometer can be used for the gravimetric procedure. For the volumetric procedure, a special Le Chatelier flask is needed.
