Bearing Capacity of Footings on Calcareous Sands
Soils and Foundations, 1990 ABSTRACT The bearing capacity and compressibility of a calcareous sand were examined by drained triaxial compression tests and laboratory model tests on strip footings 51mm by 305mm. The tests were carried out on two sands—a calcareous sand having a carbonate content of 18% and a clean sand obtained by washing the calcareous sand with Hydrochloric ...

Triaxial Mechanical Properties and Micromechanism of Calcareous Sand Modified by Nanoclay and Cement
Geofluids, 2021 Calcareous sand is developed by the fracture of marine biological skeleton under the impact of seawater. Calcareous sand is not transported in the process of deposition. Therefore, calcareous sand retains the characteristics of marine biological skeleton,
