Collapsible loess curing material and preparation method thereof
The invention relates to the technical field of soil stabilization, in particular to a collapsible loess curing material and a preparation method thereof, and the collapsible loess curing material comprises the following raw materials: loess, light calcined magnesia, magnesium sulfate heptahydrate, water and coal gangue. The preparation method comprises the following steps: firstly, respectively preparing a mixed solution A (comprising magnesium sulfate heptahydrate and water) and a dry mixture B (comprising light calcined magnesia, coal gangue and loess), and mixing and uniformly stirring the mixed solution A and the dry mixture B; and then molding, demolding and curing. The method has the characteristics of waste resource utilization, energy conservation, environmental protection, simple production process, low cost and the like, and the compressive strength of the prepared cured loess in 28d is 6.5-9.5 MPa.
土壤稳定技术领域，具体涉及一种湿陷性黄土固化材料及其制备方法，其原料为：黄土、轻烧氧化镁、七水硫酸镁、水、煤矸石。其制备方法为：首先分别制备混合溶液A（包括七水硫酸镁、水）和干混合物B（包括轻烧氧化镁、煤矸石、黄土），将二者混合并搅拌均匀；然后成型、脱模、养护。本发明具有废弃物资源利用、节能环保、生产工艺简单、成本低廉等特点，所制备的固化黄土28d的抗压强度为6.5~9.5 MPa。
