Preparation method of reduced copper slag concrete
The invention discloses a preparation method of reduced copper slag concrete. The preparation method comprises the following steps: calcining and activating copper slag at high temperature; carrying out ultramicro airflow grinding on the copper slag to form copper slag powder; taking the copper slag powder as a raw material for preparing concrete. The elasticity modulus of the concrete is improved, the shrinkage is reduced, the fracture resistance of the concrete is obviously improved, and the durability grade of the concrete is improved.
本发明公开了一种减缩型铜渣混凝土的制备方法，包括以下步骤：对铜渣高温煅烧活化；对铜渣进行超微气流粉磨，形成铜渣粉；将铜渣粉作为原料制备混凝土。提高混凝土弹性模量并减少收缩，对混凝土的抗断裂性能也有明显的改善作用，使混凝土的耐久性等级有所改善。
