Quick-setting concrete and preparation method thereof
The invention belongs to the technical field of recycling of capital construction waste and mineralized waste, and particularly discloses a quick-setting concrete and a preparation method thereof. Thequick-setting concrete comprises cement, polyester fibers, modified infrastructure garbage, modified mineralized refuse, an accelerator and a water reducing agent; the modified infrastructure garbageis formed by calcining and modifying infrastructure garbage; and the modified mineralized refuse is formed by mixing and calcining mineralized refuse, coal, a binder and an activator. The concrete setting efficiency and speed can be increased, mineralized refuse and infrastructure refuse can be reutilized, and the purpose of protecting the environment is achieved.
本发明属于基建垃圾和矿化垃圾再利用技术领域，具体公开了一种快速凝固混凝土及其制备方法，包括水泥、聚酯纤维、改性基建垃圾、改性矿化垃圾、速凝剂、减水剂；所述改性基建垃圾由基建垃圾经煅烧改性而来；改性矿化垃圾经矿化垃圾、煤、粘结剂和活化剂混合后煅烧组成。本发明不仅可加快混凝土凝固效率和速度，还能对矿化垃圾及基建垃圾进行再利用，实现保护环境的目的。
