拆除原有的建筑物，对废弃的混凝土加以利用，既可以保护环境又关系到建筑的可持续发展。将废弃的混凝土破碎再生骨料，需要建立一套工艺方法。现就目前国内比较成熟的方法是：使用膨胀剂能够制成C50的补偿收缩再生混凝土。<br/>Demolition of existent building and reclamation of abandoned concrete thereof not only protect the environment but also relate to the sustainable development of building industry. It needs an overall technology process to break abandoned concrete into reclaimed aggregate. The method which is mature in home is that: Reclaimed C50 compensation shrinkage concrete could be made by mixing with expansion additive.
