Strength of Individual Soil Aggregates Against Crushing

Strength of Individual Soil Aggregates Against Crushing

strength of individual soil aggregates, can be calculated from crushing forces if the aggregate diameters are known (13). In this test, aggregates are placed between parallel plates until aggregate failure occurs, and the aggregate tensile strength required to crush the aggregates is measured. In another test, Misra et. al. (14)
