Preparation method and application of low-carbon curing agent for saline soil treatment
The invention relates to a preparation method and application of a low-carbon curing agent for salinized soil treatment, and belongs to the field of salinized soil treatment.The preparation method includes the steps that the mixing proportion of the curing agent and salinized soil is designed, the curing agent is a mixture of a component A and a component B, and the mass ratio of the component A to the component B is (0.6-0.85): 1; the mass ratio of the curing agent to the salinized soil is (0.85-1.2): 1; meanwhile, the mass ratio of the calcium element to the silicon element is (1.0-1.4): 1, and the mass ratio of the calcium element to the magnesium element is (1.1-1.5): 1; performing drying; performing grinding; sealing and storing to obtain a curing agent product of the salinized soil. Based on the mineralization principle of CO2, the method can be used for solving the engineering diseases of salt expansion, melt sinking, easy corrosion and the like encountered in the roadbed filling process due to high contents of Mg < 2 + >, Cl <-> and SO4 < 2-> in the salinized soil area, meanwhile, the comprehensive utilization rate of solid waste is increased, green low-carbon infrastructure construction is assisted, and carbon emission is effectively reduced.
本发明涉及一种用于盐渍土处理的低碳固化剂制备方法及应用，属于盐渍土处理领域，包括：固化剂与盐渍土的配合比设计，固化剂为组分A、B的混合物，其中组分A、B的质量比为(0.6～0.85)：1；固化剂与盐渍土的质量比为(0.85～1.2)：1；同时满足：钙元素与硅元素的质量比为(1.0～1.4)：1，钙元素与镁元素的质量比为(1.1～1.5)：1；烘干；研磨；密封保存，得到盐渍土的固化剂产品。本发明基于CO2的矿化原理，可用于解决盐渍土地区高Mg2+、Cl‑、SO42‑含量导致的路基填筑过程中遇到的盐胀、溶陷，易腐蚀等工程病害，同时提升固废的综合利用水率，助力绿色低碳基础设施建设，有效降低碳排放。
