Formula of modified copper tailings applied to concrete and preparation method of modified copper tailings
According to the formula for applying the modified copper tailings to the concrete and the preparation method of the modified copper tailings, the modified copper tailings provided by the invention are firstly added with blast furnace slag, wollastonite powder and calcium oxide, so that the chemical components of the copper tailings are similar to the components of a cementing material, and the copper tailings can be fully utilized in the concrete. Secondly, the added active exciting agent can accelerate grinding and refining after the copper tailings and other auxiliary materials are ground, the hydration activity of the copper tailings and other auxiliary materials can be excited in the concrete preparation process, the concrete strength can be improved, the use of a cementing material is reduced, the cost is reduced, and the effects of energy conservation and environmental protection can be achieved. And the added polycarboxylic acid component can effectively promote infiltration between each component and the copper tailings and increase the contact area of the components, so that the respective effects of the components can be more effectively exerted. The modification of the copper tailings has good effects of resource utilization, environmental protection and energy conservation, and can replace part of cement and auxiliary materials to be applied to concrete, so that resources are saved.
本发明提供一种铜尾砂改性应用于混凝土的配方及其制备方法，本发明提供铜尾砂改性物质，首先添加了高炉矿渣、硅灰石粉、氧化钙可以使铜尾砂的化学成分近似于胶凝材料的成分，使其可以充分利用于混凝土中。其次，添加的活性激发剂使铜尾砂和其他辅料入磨之后能够加速粉磨细化，在制备混凝土时可以激发其水化活性提高混凝土强度，减少胶凝材料的使用降低成本，还可以达到节能和环保的作用。添加的聚羧酸组分可以有效促进各个组分与铜尾砂之间的浸润和增加其接触面积从而更有效的发挥其各自的作用。铜尾砂改性具有良好的资源利用，环保和节能的作用，能够替代部分水泥和辅材应用于混凝土中，节约资源。
