Method for preparing anti-seepage cushion layer by solidifying aeolian sand
The invention relates to the technical field of building materials, in particular to a method for preparing an anti-seepage cushion layer through solidified aeolian sand, and the method comprises the following steps: S1, material preparation: 55-65 parts by weight of aeolian sand, 30-40 parts by weight of building residue soil and 5-10 parts by weight of Portland cement are weighed as raw materials; s2, mixing: uniformly stirring the raw materials, then sequentially adding the thickening agent, the expanding agent, the additional water, the water reducing agent and the anti-permeability agent, and uniformly stirring again to obtain a mixed material; and S3, forming is conducted, specifically, the mixed material is pressed and formed, an aeolian sand curing material is obtained, then curing is conducted for 26-30 d, and the anti-seepage cushion layer is obtained. The aeolian sand and the building residue soil are matched for use, the aeolian sand can effectively prevent the frost heaving phenomenon, the building residue soil can promote cementation of all the components and improve the anti-seepage performance of the anti-seepage cushion layer, and the aeolian sand and the building residue soil are existing materials in the desert area, so that the transportation cost can be effectively reduced.
本发明涉及建筑材料技术领域，具体涉及一种固化风积沙制备防渗垫层的方法，包括以下步骤：S1、配料：按重量份称取风积沙55～65份，建筑渣土30～40份，硅酸盐水泥5～10份作为原料；S2、混料：将原料搅拌均匀，再依次添加增稠剂、膨胀剂、外加水、减水剂，以及抗渗剂，再次搅拌均匀，得到混合物料；S3、成型：将混合物料压制成型，得到风积沙固化料，随后养护26～30d后，即得到防渗垫层。本发明将风积沙和建筑渣土搭配使用，风积沙可有效防止冻胀现象发生，建筑渣土可以促进各组分的胶结，提高防渗垫层的抗渗性能，且风积沙和建筑渣土均为沙漠地区现有材料，可有效降低运输成本。
