Effect of grain breakage on the compressibility of soils

The compression behaviour of fine-grained soils is mainly controlled by pore collapse, while the compression behaviour of sands is mainly governed by grain breakage. For soils containing both fine and coarse soil particles such as quartz and calcite grains, the compressibility may depend on both pore collapse and grain breakage. In this study, the compressibility of two natural soils reported in the literature was first analysed in this sense,...
