摘要

随着天然砂资源日益匮乏，沙漠砂替代天然砂用于喷射混凝土成为研究热点。研究沙漠砂替代天然砂在喷射混凝土施工工艺中的适配性，对缓解资源压力、拓展混凝土材料应用具有重要意义。分析沙漠砂物理化学特性，探究其对喷射混凝土工作性能、力学性能及耐久性的影响。结果表明，经处理的沙漠砂可在一定程度上满足喷射混凝土施工要求，为沙漠砂在喷射混凝土工程中的推广应用提供理论依据与技术支持。

Abstract

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.
