摘要
为有效缓解工程用砂资源短缺的局面和加快沙漠化治理,将沙漠砂作为工程用砂制备混凝土,满足绿色发展要求。通过文献调查可知,大多学者是从沙漠砂试件或构件力学性能及耐久性等展开研究。研究结果表明:沙漠砂具有明显的地域特色,普通混凝土的理论同样适用于沙漠砂混凝土。添加矿物掺合料和纤维可以改善沙漠砂混凝土的力学性能和耐久性。
In order to effectively alleviate the shortage of sand resources for engineering and accelerate desertification control.Desert sand is used as engineering sand to prepare concrete to meet the requirements of green development.According to the literature survey,most scholars studied the mechanical properties and durability of desert sand specimens or components.The results show that desert sand has obvious regional characteristics,and the theory of ordinary concrete is also applicable to desert sand concrete.Adding mineral admixtures and fiber can improve the mechanical properties and durability of desert sand concrete.
