Phosphogypsum hydraulic cementing material as well as preparation method and application thereof
The invention provides an ardealite hydraulic cementing material as well as a preparation method and application thereof, and belongs to the technical field of cementing materials. The ardealite hydraulic cementing material provided by the invention is prepared from the following raw materials: modified ardealite particles and auxiliary active powder, and the doping amount of the modified ardealite particles is 50-95 wt%; the modified ardealite particles are obtained by modifying undisturbed ardealite particles with a calcareous material, and the mass of the calcareous material is 3-5% of that of the undisturbed ardealite particles; wherein the typical sizes of the undisturbed phosphogypsum particles are as follows: the length is 50-200 microns, and the length-diameter ratio is 1.5-5; the granularity of at least 80% of materials in the auxiliary active powder is less than or equal to 60 microns. The phosphogypsum hydraulic cementing material provided by the invention adopts a discontinuous grading particle accumulation mode, the doping amount of the modified phosphogypsum particles can reach 95 wt% at most, and a hydraulic structure can be formed after a hydration reaction, so that the phosphogypsum hydraulic cementing material can be applied to various occasions.
本发明提供了一种磷石膏水硬性胶凝材料及其制备方法和应用，属于胶凝材料技术领域。本发明提供的磷石膏水硬性胶凝材料，制备原料包括改性磷石膏颗粒和辅助活性粉体，所述改性磷石膏颗粒的掺量为50～95wt％；所述改性磷石膏颗粒由原状磷石膏颗粒经石灰质材料改性得到，所述石灰质材料的质量为原状磷石膏颗粒质量的3～5％；其中所述原状磷石膏颗粒的典型尺寸为：长度为50～200μm，长径比为1.5～5；所述辅助活性粉体中至少80％物料的粒度≤60μm。本发明提供的磷石膏水硬性胶凝材料采用间断级配颗粒堆积方式，其中改性磷石膏颗粒的掺量最高可达95wt％，且发生水化反应后能够形成水硬性结构，可以在多种场合得以应用。
