由于多种原因,产生了大量的废弃混凝土,不仅造成资源的浪费,而且污染了环境。本文综述了废弃混凝土的回收与分离技术,经处理后的废弃混凝土用于制备再生混凝土、水泥、砂浆、砌块的研究现状,指出分离技术的经济性是废弃混凝土再利用的关键问题。 Due to a variety of reasons, a large amount of waste concrete is produced, which not only causes waste of resources but also pollutes the environment. This paper reviews the technology of recycling and separating waste concrete, the research status of treated waste concrete for preparing recycled concrete, cement, mortar and block. It points out that the economy of separation technology is the key issue of reusing waste concrete.
