Phosphogypsum slope base material with balanced comprehensive performance and shear strength and preparation method of phosphogypsum slope base material
The invention discloses an ardealite slope base material with balanced comprehensive performance and shear strength and a preparation method of the ardealite slope base material. The ardealite slope base material comprises 48-62 wt% of excavation soil, 5-7 wt% of construction waste recycled aggregate, 8-23 wt% of ardealite, 0.3-0.5 wt% of perlite and 20-25 wt% of water. The preparation method comprises the following steps: putting excavation soil with various particle sizes, low-brick-concrete construction waste recycled aggregate with various particle sizes, high-brick-concrete construction waste recycled aggregate with various particle sizes and perlite into a stirrer, and stirring at a low speed to form a solid mixture; adding water into the stirrer, and stirring with the solid mixture at a low speed to form mixed slurry; adding ardealite into the stirrer, and sequentially performing low-speed stirring, high-speed stirring and low-speed stirring on the ardealite and the mixed slurry to obtain the ardealite slope base material with balanced comprehensive performance and shear strength. The problems that in the prior art, the comprehensive performance and shear strength of a slope base material are unbalanced, the production process is complex, and raw materials excessively depend on natural minerals and high-quality nutrient soil are solved.
本发明公开了一种综合性能与抗剪强度平衡的磷石膏边坡基材及其制备方法，该磷石膏边坡基材中的挖方土占48‑62wt％、建筑垃圾再生骨料占5‑7wt％、磷石膏占8‑23wt％、珍珠岩占0.3‑0.5wt％、水占20‑25wt％。该制备方法包括以下步骤：将各粒径的挖方土、各粒径的低砖混建筑垃圾再生骨料、各粒径的高砖混建筑垃圾再生骨料、珍珠岩放入搅拌机中低速搅拌，形成固体混合物；将水加入搅拌机中与固体混合物低速搅拌，形成混合料浆；将磷石膏加入搅拌机中与混合料浆依次进行低速搅拌、高速搅拌和低速搅拌，即制得综合性能与抗剪强度平衡的磷石膏边坡基材。本发明解决了现有技术中边坡基材的综合性能与抗剪强度不平衡、生产工艺复杂、原材料过度依赖天然矿物和优质营养土等问题。
