Preparation method of expansive soil roadbed filler simply modified by titanium gypsum
The invention provides a preparation method of an expansive soil roadbed filler simply modified by waste titanium gypsum, and relates to the technical field of geotechnical engineering. According to the method, titanium gypsum powder subjected to simple physical modification is used as a curing agent to improve the expansive soil roadbed; the titanium gypsum is doped into the expansive soil, the water content is controlled to be 18%-20%, the mixture is fully stirred to be uniform, and the mass of the dry titanium gypsum accounts for 20%-25% of the mass of the dry expansive soil. The cost of the curing agent can be reduced, resource utilization of solid waste titanium gypsum can be achieved, and good economic benefits and social benefits are achieved.
本发明提供了一种废弃钛石膏简易改性改良膨胀土路基填料的制备方法，涉及岩土工程技术领域。该方法用经过简单物理改性后的钛石膏粉末作为固化剂改良膨胀土路基；将钛石膏掺加到膨胀土中，控制含水率为18％‑20％，充分搅拌，使其均匀，干钛石膏的质量为膨胀土干土质量的20％‑25％。本发明不仅可以降低固化剂成本，更能实现固体废弃物钛石膏的资源化利用，具有较好的经济效益及社会效益。
