机制砂在高性能混凝土中的应用研究

Application Research of Mechanical Sand in High Performance Concrete

随着我国社会经济的快速发展,各项基础设施建设都在不断地完善,在此过程中就会用到大量的建筑砂,我国每年的建筑砂用量在世界上都排在前几位,每年的消耗量可以达到50亿m3左右。天然砂作为一种不可再生资源,在我国的分布也不够均匀,在具体的开采过程中如果没有进行严格的管理就可能会给自然环境造成非常严重的破坏,想要对自然和资源和环境进行有效的保护,同时有效降低施工成本提升其使用性能就应该尽可能减少对天然砂的使用,而应该采用机制砂作为施工的主要材料,只有这样才能获得更加长久的发展。

With the rapid development of China＇s social economy, various infrastructure constructions are constantly improving. In the process, a large amount of construction sand will be used. The annual amount of construction sand in China is ranked in the top in the world. The consumption can reach about 5 billion m3 one year. As a non-renewable resource, natural sand is not evenly distributed in China. In the specific mining process, if it is not strictly managed, it may cause very serious damage to the natural environment. To effectively protect natural resources and the environment, reduce construction costs and improve its performance, it is necessary to minimize the use of natural sand. Instead, mechanical sand should be used as the main material for construction. Only in this way can we achieve more long-term development.
