Composite cement retarder and preparation method thereof as well as retarding cement and preparation method thereof
The invention discloses a composite cement retarder, a preparation method of the composite cement retarder, retarding cement and a preparation method of the retarding cement, and belongs to the technical field of cement retarders. The composite cement retarder is prepared from the following raw materials in parts by weight: 10-25 parts of fluorite tailings, 0.1-0.8 part of red mud and 3-8 parts of phosphorus slag. The preparation method of the composite cement retarder comprises the following steps: preparing the raw materials in parts by weight, grinding and uniformly mixing to obtain the composite cement retarder. The retarding type cement provided by the invention comprises the composite cement retarder. The composite cement retarder is prepared from the fluorite tailings, the red mud and the phosphorus slag, the retarder has a good retarding effect, and the burnability and the mechanical property of cement can be improved. The raw materials are easy to obtain, tailing resources are fully utilized, secondary utilization of the resources is achieved, and the method is worthy of application and popularization.
本发明公开了复合水泥缓凝剂及其制法、缓凝型水泥及制法，属于水泥缓凝剂技术领域。本发明的复合水泥缓凝剂，由包括以下重量份的原料制成：萤石尾矿10‑25份，赤泥0.1‑0.8份，磷渣3‑8份。本发明的复合水泥缓凝剂的制备方法包括以下步骤：按重量份准备各原料，研磨，混匀，得到所述复合水泥缓凝剂。本发明的缓凝型水泥，包括上述的复合水泥缓凝剂。本发明采用萤石尾矿、赤泥和磷渣制备复合水泥缓凝剂，该缓凝剂具有良好的缓凝作用，并且还能提高水泥的易烧性能和力学性能。本发明的原料易得，充分尾矿资源，实现了资源的二次利用，值得推广应用。
