随着我国经济的快速发展,城市化进程日益加快,混凝土的使用越来越广泛,一方面伴随着混泥土的大量使用,骨料的开采带来了一系列的问题,例如水土流失、植被破坏、山体滑坡,对环境产造成了巨大的破坏。另一方面,由于大量建筑物的拆除和混凝土老化和破坏,目前我国的每年废弃的建筑垃圾到达80亿吨,并且以每年仍然在以3亿吨的速度快速增长,这些废旧混凝土给环境也产生了严重威胁。建筑垃圾骨料又被称为再生骨料,以再生骨料部分或全部取代天然骨料来设计配置的混凝土称为再生混凝土,再生混凝土技术可实现对建筑垃圾的回收利用,对于保护环境、节约资源、发展生态建筑具有重要意义。
With the rapid economic development in our country, the process of urbanization is accelerating day by day. The use of concrete is more and more widespread. On the one hand, with the extensive use of concrete, aggregate mining has brought a series of problems such as soil erosion, vegetation damage Landslides caused tremendous damage to the environment. On the other hand, due to the demolition of a large number of buildings and the aging and destruction of concrete, at present, China’s annual waste construction waste reaches 8 billion tons and is still growing rapidly at a rate of 300 million tons per annum. The used concrete also gives the environment A serious threat. Construction waste aggregates, also known as recycled aggregates, designed to replace or partially replace natural aggregates with recycled aggregate, are referred to as recycled concrete. Recycled concrete technology can be used to recycle and reuse construction waste, Resources, the development of ecological architecture is of great significance.
