Concrete active regenerated micro powder and preparation method thereof
The invention provides concrete active regenerated micro powder and a preparation method thereof, and belongs to the field of building material solid waste resource utilization. The method comprises the following steps: crushing, screening, grinding and sieving waste concrete in sequence to obtain unactivated regenerated micro powder; and performing microwave excitation on the non-activated regenerated micro-powder to obtain the concrete active regenerated micro-powder. The activity of the regenerated micro-powder is improved through microwave excitation, the regenerated micro-powder can be used for preparing high-quality concrete, and the compressive strength of the concrete is improved while the cement consumption is reduced. According to the concrete, efficient resource utilization of waste concrete can be effectively achieved, outdoor placement and landfill are avoided, recycling of waste resources is achieved, and meanwhile the concrete has environmental protection significance.
本发明提供了一种混凝土活性再生微粉及其制备方法，属于建筑材料固废资源化利用领域。本发明将废弃混凝土依次经过破碎、筛分、研磨和过筛得到未活化再生微粉；将未活化再生微粉通过微波激发得到混凝土活性再生微粉。本发明利用微波激发提升再生微粉活性，可用于制备高质量混凝土，减少水泥使用量的同时提高了混凝土的抗压强度。这种混凝土可有效解决废弃混凝土的高效资源化利用，使采用避免露天放置和填埋，实现废弃资源的再利用，同时也具有环保意义。
