沙漠砂混凝土研究进展

Research progress of desert sand concrete

天然细骨料匮乏问题是目前建筑工程领域所面临的难题,寻找一个能替代天然细骨料的资源已经成为主流研究课题。作为一种新型建筑材料,沙漠砂(风积砂)资源丰富,若能充分利用其资源能够缓解当天然细骨料供不应求的局面,满足可持续发展理念。主要根据目前的国内外沙漠砂混凝土研究现状,分析了沙漠砂混凝土基本力学性能和耐久性、沙漠砂混凝土构件力学性能以及改良措施。在此基础上,结合目前的研究现状,对沙漠砂混凝土未来的研究前景进行了分析和展望,为其在工程应用和推广中提供参考。

The shortage of natural fine aggregates is a difficult problem in the field of construction engineering.Finding a resource that can replace natural fine aggregates has become a mainstream research topic.As a new type of construction material,desert sand(aeolian sand)is rich in resources.If its resources can be fully utilized,it can alleviate the shortage of natural fine aggregates and meet the concept of sustainable development.Based on the current research status of desert sand concrete at home and abroad,it analyzes the basic mechanical properties and durability of desert sand concrete,the mechanical properties of desert sand concrete components and improvement measures.On this basis,combined with the current research status,the future research prospects of desert sand concrete are analyzed and prospected to provide reference for its application and promotion in engineering.
