机制砂石的应用与发展综述

Review on application and development of manufactured sand and gravel

砂石作为工程建设中最基本且不可或缺的建筑材料,自然资源消耗量巨大,且传统河砂滥采偷采严重破坏生态环境,危及防洪安全.通过研究国内机制砂石和国家相关政策,综述国内机制砂石的应用优势、市场现状及存在的问题,对国内机制砂石的应用和发展作出展望,为我国机制砂石行业的健康有序发展提供参考.

As the most basic and indispensable building materials in engineering construction,the consumption of natural resources is huge,and the excessive and illegal mining of traditional river sand seriously destroys the ecological environment and endangers the safety of flood control.By studying domestic manufacture sand gravel and relevant national policies,the paper summarizes the application advantages,market status and existing problems of domestic manufacture sand and gravel,and looks forward to the application and development of domestic manufacture sand and gravel,so as to provide reference for the healthy and orderly development of China's manufacture sand and gravel industry.
