Road base material containing industrial solid waste titanium slag and preparation method thereof
The invention discloses a road base material containing industrial solid waste titanium slag and a preparation method thereof, and relates to the technical field of roads and municipal engineering roads, and the preparation method comprises the following steps: S01, obtaining an optimal titanium slag coarse and fine aggregate gradation through a corresponding gradation design method and related performance tests to meet the requirement that the material forms a dense skeleton structure; s02, preparing cement and drinking water; s03, the titanium slag, cement and drinking water are put into mixing equipment to be mixed, and the road base material is obtained. According to the road base material, the industrial solid waste titanium slag is used for replacing gravel to prepare the road base material, the titanium slag plays a role in providing a framework for the road base material, meanwhile, the titanium slag has certain activity, and then through a reasonable coarse and fine aggregate grading design method, the road base material forms a framework compact structure; therefore, the road base material can obtain higher unconfined compressive strength and lower shrinkage rate, the shrinkage coefficient of the road base material is reduced, the overall bearing capacity of the road base is further improved, and the service life of the road base is further prolonged. In addition, resource utilization of industrial solid waste titanium slag can be realized.
本发明公开了一种含工业固废钛矿渣的道路基层材料及其制备方法，涉及公路和市政工程道路技术领域，包括如下步骤：S01、通过相应级配设计方法以及相关性能测试得到最优的钛矿渣粗细骨料级配，用以满足材料形成骨架密实型结构；S02、准备水泥和饮用水；S03、将钛矿渣、水泥和饮用水放入拌合设备中进行拌和，得到道路基层材料。本发明中该材料使用工业固废钛矿渣替代砂石制备道路基层材料，钛矿渣起到为道路基层材料提供骨架的作用，同时钛矿渣具备一定的活性，再通过合理的粗细骨料级配设计方法，使得道路基层材料形成骨架密实性结构，道路基层材料便可以获得更高的无侧限抗压强度和更低的收缩率，道路基层材料的收缩系数减小，进一步提高道路基层的整体承载力与使用寿命。另外，也可以实现工业固体废弃物钛矿渣的资源化利用。
