废弃混凝土再生利用技术是发展绿色混凝土,实现建筑、资源、环境可持续发展的必然要求和主流趋势,是推动建筑垃圾资源化进程的有效途径。结合我国资源紧缺及环境污染严重的现状,从生态效益、经济效益、社会效益方面分析了废弃混凝土再生利用的必要性及可行性。通过查阅和研究大量文献,对国内外再生混凝土的研究动态与应用情况进行了深入剖析和对比,综述了再生混凝土基本力学性能、耐久性能及变形性能,对废弃混凝土再生利用技术前景进行了展望。
Abandoned concrete recycling technology is the inevitable requirement and mainstream trend of developing green concrete to realize the sustainable development of construction, resources and environment, and is an effective way to promote the recycling of construction waste. According to the current situation of resource shortage and serious environmental pollution in our country, the necessity and feasibility of waste concrete recycling are analyzed from the aspects of ecological benefits, economic benefits and social benefits. Through reviewing and studying a large number of documents, the research status and application of recycled concrete at home and abroad are deeply analyzed and compared. The basic mechanical properties, durability and deformation properties of recycled concrete are reviewed. The prospect of recycling technology of waste concrete is prospected.
