Paste filling material
The invention relates to a paste filling material. The paste filling material is prepared from the following raw material components: a red mud-based active material, first red mud, a pumping agent and a stabilizer, wherein the red mud-based active material is obtained by sintering dealkalized red mud and industrial byproduct gypsum, and the raw material components of the dealkalized red mud comprise second red mud and slag rich in calcium oxide. The red mud is converted into the paste filling material through two times of gradient utilization, the paste filling material has the advantages of being simple in process, low in cost and good in fluidity, high in mechanical strength, micro-expansive and the like, the performance requirement of the mine filling material is met, and high-dosage utilization of the red mud in the field of filling materials is achieved.
本申请涉及一种膏体充填材料，所述膏体充填材料的原料组分包括：赤泥基活性物料、第一赤泥、泵送剂以及稳定剂；其中，所述赤泥基活性物料由脱碱赤泥与工业副产石膏烧结得到，所述脱碱赤泥的原料组分包括第二赤泥和富含氧化钙的渣料。本申请内容通过两次梯级利用将赤泥转化成膏体充填材料，具有工艺简单、成本低的优势以及流动性好、力学强度高、微膨胀等优良性能，达到了矿山充填材料的性能要求，实现了赤泥在充填材料领域的高掺量利用。
