Advances in Constructional Engineering

As natural sand resources become increasingly scarce, desert sand has been used as an alternative to natural sand in shotcrete applications, making it a research hotspot. Studying the compatibility of desert sand with natural sand in shotcrete construction techniques is crucial for alleviating resource pressure and expanding the application of concrete materials. This study analyzes the physicochemical properties of desert sand and explores its impact on the workability, mechanical properties, and durability of shotcrete. The results show that treated desert sand can meet the construction requirements of shotcrete to some extent, providing theoretical basis and technical support for the promotion and application of desert sand in shotcrete projects.
