Preparation method of modified ardealite roadbed material
The invention relates to the technical field of geotechnical engineering, and discloses a preparation method of a modified ardealite roadbed material, which comprises the following steps: step 1, preparing a dry material of the modified ardealite roadbed material; slaked lime is obtained after quick lime is cured, then the slaked lime is added into ardealite to be evenly stirred, and a modified ardealite roadbed material dry material is prepared; step 2, preparing a wet material of the modified phosphogypsum roadbed material; adding water glass into water, and uniformly stirring to obtain a water and water glass mixed solution; and adding the mixed solution into the modified phosphogypsum roadbed material dry material prepared in the step 1. The lime and the water glass are added into the phosphogypsum to prepare the modified phosphogypsum roadbed material, and the modified phosphogypsum roadbed material is applied to road roadbed engineering construction, so that the problem of random accumulation and discharge of a large amount of solid waste phosphogypsum is reduced, the pollution of the phosphogypsum to the surrounding environment is reduced, and the comprehensive utilization level and the resource utilization efficiency are improved.
本发明涉及岩土工程技术领域，公开了一种改性磷石膏路基材料的制备方法，包括如下步骤：步骤1、制备改性磷石膏路基材料干料；由生石灰经熟化后得到熟石灰，然后将熟石灰加入到磷石膏中搅拌均匀，制备而成改性磷石膏路基材料干料；步骤2、改性磷石膏路基材料湿料的制备；将水玻璃加入到水中，搅拌均匀，得到水和水玻璃混合液；将所述混合液加入到步骤1制得的改性磷石膏路基材料干料中。本发明将石灰、水玻璃加入到磷石膏中制得改性磷石膏路基材料，并应用于道路路基工程建设中，减少了大宗固体废弃物磷石膏的任意堆积排放问题，降低了磷石膏对周边环境的污染，提高了综合利用水平、资源利用效率。
