Anhydrous gypsum novel mortar phosphogypsum cemented filling body and preparation method thereof
The invention belongs to the technical field of novel mortar, and particularly relates to a novel anhydrite mortar ardealite cemented filling body and a preparation method thereof. The influence of the replacement ratio of the anhydrous gypsum, the mass concentration of slurry and the bone-glue ratio on the performance of the phosphogypsum cemented filling body of the existing novel anhydrous gypsum mortar is researched by changing preparation conditions, and a gelatinizing agent formula is modified in order to further optimize the hydration performance of the existing novel anhydrous gypsum mortar and improve the strength of the filling body. And the influence of the adding amount of the excitant under the condition of the new formula is explored.
本发明属于新型砂浆技术领域，具体涉及一种无水石膏新型砂浆磷石膏胶结充填体及其制备方法。通过改变制备条件研究了无水石膏替代比、料浆质量浓度和骨胶比对现有无水石膏新型砂浆磷石膏胶结充填体性能的影响，为进一步优化现有无水石膏新型砂浆水化性能，提升充填体强度，改性了胶凝剂配方，并探索新配方情况下激发剂的添加量影响。
