Composite curing agent and method for improving sulfate salinized soil by using composite curing agent
The invention relates to the technical field of soil improvement and remediation, and discloses application of a composite curing agent, and the composite curing agent is used for improving sulfate saline soil. The invention further provides an application method of the composite curing agent. The application method comprises the following steps: pretreating a soil sample of the sulfate saline soil; before a test, a soil sample is firstly pretreated, the soil sample is firstly air-dried to ensure that moisture in the soil sample is fully volatilized so as to avoid influence on a subsequent test, then the air-dried soil sample is crushed into fine particles, and the fine particles are screened by a 2mm screen so as to ensure that the granularity of the soil sample is uniform and consistent and facilitate subsequent mixing and preparation. The composite curing agent provided by the invention can improve the sulfate salinized soil, and the salinized soil improved by the composite curing agent has the advantages that the salt expansion deformation is reduced, the early strength is high, the water stability is good, the treated solidified soil meets the engineering use standard, the industrial waste is fully utilized, and the like.
本发明涉及土壤改良修复技术领域，公开了一种复合固化剂的应用，利用上述复合固化剂改良硫酸盐渍土。本发明还提出了一种复合固化剂的应用方法，包括如下步骤：硫酸盐渍土的土样预处理；在试验之前，首先进行土样的预处理工作，先对土样进行风干，确保其内部的水分被充分挥发，以免对后续试验造成影响，接着将风干的土样碾碎成细小的颗粒，并通过2毫米的筛网进行筛选，以确保土样的粒度均匀一致，便于后续的混合与制备。本发明提出的复合固化剂能够改良硫酸盐渍土，经复合固化剂改良处理后的盐渍土具有减少盐胀变形、早期强度高、水稳定性好，处理后的固化土符合工程使用标准以及充分利用工业废弃物等优点。
