Waste concrete composite ardealite-based electrochemical synthetic cement and preparation method thereof
The invention discloses waste concrete composite ardealite-based electrochemical synthetic cement and a preparation method thereof, the preparation method comprises the following steps: S1, pretreating waste concrete to obtain waste concrete with a target particle size; s2, adding water into the waste concrete, and uniformly stirring to obtain waste concrete slurry; s3, the waste concrete slurry is electrolyzed, and carbon dioxide and electrolysis products generated by electrolysis are collected; s4, adding water, waste soil and ardealite into the electrolysis product, uniformly stirring, and adjusting the pH value to be acidic, so as to obtain calcium ion slurry; s5, the calcium ion slurry is heated under the stirring condition, stirring and heating are stopped after the calcium ion slurry is completely converted into cement, natural cooling and curing are conducted, and cement clinker is obtained; s6, the cement clinker is ground and packaged, and the waste concrete composite phosphogypsum-based electrochemical synthesis cement is obtained. According to the invention, the cement with excellent performance can be prepared at a lower temperature, and the energy consumption is greatly reduced.
本发明公开了一种废弃混凝土复合磷石膏基电化学合成水泥及其制备方法，所述制备方法包括以下步骤：S1：对废弃混凝土进行预处理，获得目标粒度的废弃混凝土；S2：向所述废弃混凝土中加入水，搅拌均匀获得废弃混凝土浆体；S3：对所述废弃混凝土浆体进行电解，收集电解产生的二氧化碳和电解产物；S4：向所述电解产物中加入水、废弃土和磷石膏，搅拌均匀并调节pH至酸性，获得钙离子浆液；S5：对所述钙离子浆液在搅拌条件下进行加热，完全转化为水泥后停止搅拌和加热，自然冷却并熟化，获得水泥熟料；S6：对所述水泥熟料进行粉磨和包装，获得废弃混凝土复合磷石膏基电化学合成水泥。本发明能够在较低的温度下制得性能优异的水泥，大大降低能耗。
