再生混凝土作为绿色建筑材料的基本性能与发展趋势

目前,我国基本建设速度不断加快,建筑面积不断扩大。然而,伴随着建筑物的新建、改造、拆除、重建,混凝土材料用量巨大,不仅造成了资源和能源的大量消耗,同时还造成了环境污染,直接影响人类的生产生活和可持续发展。再生混凝土作为一种绿色建筑材料,不仅可以从源头解决废弃混凝土的处理问题,同时节约了天然骨料资源,缓解了供需矛盾,极大地满足了可持续发展要求,具有显著的社会效益、经济效益和环保效益。本文通过对再生混凝土的基本性能的表述,阐明了其工程应用的可行性,并通过大量阅读、调查、整理关于再生混凝土的资料,进一步找出了再生混凝土的发展趋势,为后续研究提供理论保障。

The Basic Performance and Development Trend of Recycled Concrete as Green Building Materials

At present, the basic construction speed of our country accelerate constantly, the construction area expands unceasingly. However, along with the new- built, renovation, demolition and reconstruction of the buildings, the consumption of concrete material is great, which not only brought out a large number of resources and energy consumption, but also caused environment pollution, affected human life and sustainable development directly. The recycled concrete as a kind of green building materials, on the one hand, can solve the processing problem of waste concrete from the source, and save the natural aggregate resources at the same time, which can relieve the contradiction between supply and demand, meet the requirement of the sustainable development enormously, and would have significant social benefit, economic benefit and environmental benefit. This paper elaborated the basic properties of the recycled concrete, illustrated the feasibility of its engineering application, and found out the trend of the recycled concrete through reading,investigating and sorting great mass of recycled concrete data, which would provide theoretical guarantee for further research.
