Objective To develop a scientific method for identifyingsea sand to differentiate it from river sand. Methods Qualitative andquantitative analysis of sea sand is conducted through its sensorycharacteristics, microscopic features, chemical and physical properties,and volumetric measurement methods. Results The chemical analysis showsthat sea sand is different from river sand with high chloride content(≥0.01%) and high shell content (≥0.1%). The electrical conductivity ofsea sand is significantly higher than that of river sand. In terms ofquantitative analysis, the relative deviation of the sea sand weightcalculation method proposed in this study is ${0.25}\%\sim {0.87}\%$ , which is close tothe allowable error of $\pm {0.3}\%$ of the truck scale. Conclusion The identification method proposed inthis study can quickly and effectively distinguish sea sand, which is ofgreat significance in ensuring the safety of building materials.
