    Strength of Individual Soil Aggregates Against Crushing

    The shape of an aggregate is very important in crushing tests. Dexter and Kroesbergen 13 emphasized that a major source of variation in crushing force was due to the variability in aggregate shape. In general, researchers working on aggregate strength against crushing forces have assumed that the shape of aggregates is spherical 10.
