关于特/超细砂混凝土研究现状及发展前景的思考

Research status and development prospect of superfine sand concrete

为有效缓解河砂资源短缺与基础设施快速发展的矛盾,降低大肆开采对生态环境的影响,将特/超细砂部分或者全部作为细骨料制备特/超细砂混凝土,满足绿色发展要求。由文献调查可知,目前特/超细砂混凝土研究处于快速发展阶段,相关学者通过对其基本力学性能、耐久性以及构件的工作性能等的探究,以期推动特/超细砂混凝土在工程实践中的应用。

In order to effectively alleviate the contradiction between the shortage of river sand resources and the rapid development of infrastructure,and reduce the impact of wantonly mining on the ecological environment,the superfine sand concrete is prepared by using part or all of the superfine sand as fine aggregate to meet the requirements of green development.According to the literature survey,at present,the research of ultra-fine sand concrete is in the rapid development stage.Through the exploration of its basic mechanical properties,durability and working performance of components,the relevant scholars hope to promote the application of superfine sand concrete in engineering practice.
