Phosphogypsum pottery sand composite road base material and preparation method thereof
The invention relates to the field of road base materials, and particularly discloses a phosphogypsum pottery sand composite road base material and a preparation method thereof. The phosphogypsum and pottery sand composite road base material is prepared from the following raw materials in parts by weight: 100 to 110 parts of modified phosphogypsum powder, 10 to 16 parts of pottery sand, 18 to 24 parts of water, 0.2 to 0.4 part of a retarder, 0.2 to 0.4 part of a waterproof agent, 0.5 to 1.5 parts of pupa shells and 0.5 to 1.5 parts of wollastonite. The ardealite and pottery sand composite road base material provided by the invention has good compression resistance, freezing resistance and water resistance, the content of the ardealite and the pottery sand reaches 90% or above, comprehensive utilization of the waste ardealite and the regenerated pottery sand is realized, resources are saved, and environmental protection is facilitated.
本申请涉及道路基层材料领域，具体公开了一种磷石膏陶砂复合道路基层材料及制备方法，所述磷石膏陶砂复合道路基层材料由以下重量份的原料制备得到：改性磷石膏粉100‑110份、陶砂10‑16份、水18‑24份、缓凝剂0.2‑0.4份、防水剂0.2‑0.4份、蛹壳0.5‑1.5份、硅灰石0.5‑1.5份。本申请提供的磷石膏陶砂复合道路基层材料具有良好的抗压、抗冻、抗水性能，且其中磷石膏和陶砂的含量达到了90%以上，实现了废弃磷石膏和再生陶砂的综合利用，节约资源，利于环保。
