国外再生混凝土的应用概述及技术标准

Application Overview and Technical Standards of Recycled Concrete in Other Countries

随着环保意识的不断深化,世界各国都在加强废混凝土再生利用的技术研究.日本、美国、德国等国家凭借经济实力与科技优势,发展了许多再生骨料制备技术及再生混凝土应用技术,有的国家已制定了相应的技术标准,并得到了推广应用.通过对国外废混凝土再生利用概况以及再生混凝土的技术标准进行文献调查,分析研究了国外再生混凝土的发展趋势,为我国再生混凝土技术的推广应用及相应规范的制定提供参考依据.

With the continuous deepening of environmental awareness, the technical researches with circulation utilization of waste concrete were enhanced in many countries in the world. Rely on the economic strength and technology advantages, some countries developed a number of manufacture technology of recycled aggregate and application technology of recycled concrete such as Japan, the Unite States and Germany and so on. In some countries, they have developed the appropriate technical standards, and have been extended and applied. The tendency of recycled concrete in some foreign countries was analysised and researched by investigating the circulation utilization of waste concrete and the technical standards of recycled concrete in this paper. The objectives were to provide the reference for the application of recycled concrete technology and the formulation of corresponding standard for China.
