对公路的结构物的重建工程中所获砼拆毁碎块的重复利用问题已经考虑了许多年,将拆毁的砼作为再生骨料,有助于克服环境和经济问题,利用砼的废弃物可节省天然优质骨料资源。对再生骨料制备的砼的质量问题的研究,已在文献资料中作了回顾。 多数研究者都是在有控制的实验室条件下制备原始砼的。在本研究中所用的再生骨料,则是从两项重建工程中获得的现场拆毁砼。利用同样级配天然骨料和再生骨料制备的砼的力学性能,已在上一篇论文中报道过了。
Many years have been considered for the reuse of rafts that have been destroyed in the reconstruction of highway structures. The demolitions used as recycled aggregates will help overcome environmental and economic problems, and the use of raft waste can save energy. Natural high quality aggregate resources. The study of the quality of thorium prepared from recycled aggregates has been reviewed in literature. Most researchers prepare raw cesium under controlled laboratory conditions. The recycled aggregates used in this study were field demolition defects obtained from two reconstruction projects. The mechanical properties of thorium prepared using the same grading of natural aggregates and recycled aggregates have been reported in a previous paper.
