Dynamic properties of mortar with oyster shell sand replacement.

ABSTRACT: With the rapid expansion of construction engineering, the demand for traditional materials, particularly natural river sand, has surged, resulting in excessive resource exploitation and significant ecological damage. In response, the use of waste oyster shells as a sustainable alternative for fine aggregates has gained attention. However, limited research has been conducted on the dynamic properties of mortar with this substitution. This study explores the potential of using crushed oyster shell sand (OSS) as fine aggregates in mortar. A series of Split Hopkinson Pressure Bar (SHPB) tests under different gas pressures (p_g) (0.2, 0.3, and 0.4 MPa) were carried out on mortar samples with five OSS replacement ratios (R_r) (0%, 20%, 50%, 80%, and 100%), using a water-to-ce
