Crushing Of Calcareous Sands During Shear

ABSTRACT. Calcareous sands often consist of skeletal remains of marine organisms. Intraparticle voids exist in such sands. These tend to crush more readily under stress than terrigeneous sands. This paper presents laboratory triaxial test data for low and elevated cell pressures up to 64 kgfcm2 for four calcareous sands from the west coast of …
