摘要
我国沙漠资源丰富,随着我国基础建设的不断发展,对于用砂需求量不断增加,而目前的砂大多采用的是河砂,这造成了河砂资源的短缺,为有效缓解建设用砂的供需矛盾,采用沙漠砂替换或部分替换河砂制备沙漠砂混凝土,既可满足绿色发展要求,又极大地缓解了砂的供需矛盾,因此,沙漠砂混凝土的力学性能成为研究的热点。回顾总结了沙漠砂混凝土的主要力学性能,并对目前提出的沙漠砂混凝土抗压本构模型进行了梳理,最后提出了沙漠砂混凝土的发展展望及有价值的研究方向。
China is rich in desert resources.With the continuous development of China's infrastructure,the demand for sand is increasing,and most of the current sand is river sand,which causes a shortage of river sand resources.To effectively alleviate the contradiction between supply and demand of construction sand,desert sand is used to replace or partially replace the river sand for the preparation of desert sand concrete,which can meet the requirements of the green development,but also greatly alleviate the contradiction between the demand and supply of sand.Therefore,the mechanical properties of desert sand concrete have become a hot research topic.The main mechanical properties of desert sand concrete are reviewed and summarized,the compressive constitutive model of desert sand concrete is sorted out,and finally,the development prospect and valuable research direction of desert sand concrete are proposed.
