All-solid waste phosphogypsum-based aggregate as well as preparation method and application thereof
The invention discloses an all-solid waste ardealite-based aggregate as well as a preparation method and application thereof, and belongs to the technical field of artificial aggregates of building materials. The method comprises the following steps: adding water into a granulation material, pre-stirring to obtain a premix, and granulating the premix to obtain water-drop-state green pellets; continuing to add a granulation material or a reconstruction material into the water-drop-state green pellets, reconstructing the water-drop-state green pellets, and then continuing to perform granulation to obtain capillary-state green pellets; and maintaining the capillary green pellets to obtain the all-solid waste phosphogypsum-based aggregate. According to the invention, granulation materials and water are mixed, so that the water consumption for granulation can be quantitatively controlled, and the granulation quality and efficiency are remarkably improved; in addition, by adding a granulation material or a reconstruction material, the water-drop-state green pellets are reconstructed, so that the process is simplified, and the adaptability of the aggregate and Portland cement can be remarkably improved.
本发明公开了一种全固废磷石膏基集料及其制备方法和应用，属于建筑材料人造集料技术领域。该方法包括如下步骤：将造粒物料加水预搅拌，得到预混物，然后对预混物进行造粒，得到水滴态生球；向水滴态生球中继续加入造粒物料或重构物料，对水滴态生球进行重构，然后继续进行造粒，得到毛细态生球；将毛细态生球进行养护，得到全固废磷石膏基集料。本发明通过先将造粒物料和水混合，可实现定量控制造粒的用水量，从而显著提高造粒质量和效率；另外，通过加入造粒物料或重构物料，对水滴态生球进行重构，不仅简化工艺，还可以显著改善集料与硅酸盐水泥的适应性。
