日本的清水建设公司与东京电力公司研制出用报废大楼等建筑物解体工程中所产生的废弃混凝土,经粉碎、加热、摩擦等加工处理,再生为高品质的骨料技术已实用化。这种再生的混凝土骨料,在质量上与天然骨料有同样的功能,可用于楼房混凝土结构物使用。 Japan’s Shimizu Construction Company and Tokyo Electric Power Company have developed waste concrete produced in the dismantling of buildings such as scrapped buildings, and have been put into practical use by pulverizing, heating, rubbing and other processing to regenerate high-quality aggregates. This recycled concrete aggregate, with the same quality of natural aggregate, can be used for building concrete structures.
