Completely recyclable concrete as well as preparation method and circulation method thereof

The preparation method comprises the following steps: fully and uniformly mixing Portland cement, limestone coarse aggregate, river sand, limestone machine-made sand, copper slag, metakaolin and a water reducing agent, adding water, and uniformly stirring to obtain the concrete capable of being completely recycled. The concrete capable of being completely recycled can be directly regenerated into high belite cement clinker and recycled after being crushed and calcined after serving, and the obtained cement clinker is good in hardening performance and low in calcination temperature. 本发明公开一种可完全循环混凝土及其制备方法与循环方法，将硅酸盐水泥、石灰岩质粗集料、河砂、石灰岩质机制砂、铜渣、偏高岭土、减水剂充分混合均匀，加入水搅拌均匀，得到可完全循环混凝土，所述可完全循环混凝土服役结束后经粉碎煅烧，可直接再生为高贝利特水泥熟料并进行循环使用，且得到的水泥熟料硬化性能好、煅烧温度低。
