Non-delayed coagulation phosphorus slag powder for cement-based material and preparation method thereof
The invention discloses retarding-free phosphorus slag powder for a cement-based material and a preparation method thereof and belongs to the technical field of building materials. The method comprises the following steps: carrying out wet grinding on the water-quenched phosphorus slag, mixing and stirring the water-quenched phosphorus slag, an anion capturing agent, water and an alkaline regulator, removing foam during stirring, and filtering and drying the mixture to obtain the water-quenched phosphorus slag. Through treatment and preparation of the phosphorus slag powder, the problem of delayed coagulation of the phosphorus slag powder on a cement-based material can be effectively solved, and the current situation that the phosphorus slag powder is poor in early strength is improved. The preparation method is simple in process, the use amount of various auxiliaries is extremely low, and the influence on the production cost of the phosphorus slag powder is extremely small; therefore, the method has wide applicability and excellent economic benefits in production practice.
本发明公开了一种水泥基材料用无缓凝磷渣粉及其制备方法，属于建筑材料技术领域。其包括以下步骤：对水淬磷渣湿磨，与阴离子捕捉剂、水和碱性调节剂混合搅拌，除去搅拌中的泡沫后过滤烘干，即得。本发明通过对磷渣粉的处理和制备，能够有效解决磷渣粉对水泥基材料的缓凝问题，改善磷渣粉早期强度差的现状，制备方法工艺简单，且各种助剂用量极低，对磷渣粉的生产成本影响极小，在生产实践中具有广泛的适用性和优异的经济效益。
