Monotonic Behavior of Calcareous Sands with Increasing Particle Crushing
Calcareous sands, comprising higher than 50% calcium carbonate, are mostly located between latitude 30°S and 30°N. The engineering properties of calcareous sands differ from those of clays and silica sands due to the high particle angularity and in situ void ratios. Investigation of calcareous sands properties and stress-strain response are required for the design and long-term maintenance of offshore infrastructure including piers, bridges, and offshore renewable energy structures. In this research, calcareous sands from Puerto Rico are investigated to determine the monotonic stress-strain response and how increasing severities of particle damage and crushing affect loading behavior. To accomplish this, several advanced laboratory tests were conducted: 1) triaxial tests (CU) were utilized to investigate the monotonic stress-strain behavior; 2) oedometer tests, providing the one-directional compression load for sand crushing. The calcareous specimens were tested under various confining pressures (σ3) and with increasing percentages of crushed material.
