Abstract

The invention relates to a high-humic-acid soft soil curing agent adopting a solid waste inorganic binder and a preparation method of the high-humic-acid soft soil curing agent, and belongs to the technical field of curing agents. Comprising the following raw materials in parts by weight: 40-50 parts of an inorganic binding material, 6-8 parts of an exciting agent, 6-10 parts of an ion replacing agent, 8-10 parts of a humic acid modifier, 8-10 parts of a water repellent, 5-8 parts of an early strength agent, 6-10 parts of a water reducing agent, 5-8 parts of a filling agent and 5-8 parts of an air entraining agent. The invention has the following effects and advantages: when the soil containing humic acid is cured, the traditional cement is often low in strength due to the existence of humic acid. According to the invention, the influence of humic acid on soil solidification is especially solved, good economic benefits and environmental benefits are achieved, and the aspects of strength, durability, waterproofness and the like are also powerfully guaranteed.

Description

technical field [0001] The invention belongs to the technical field of curing agents, in particular to a high humic acid soft soil curing agent using solid waste inorganic binders and a preparation method thereof. Background technique [0002] In order to meet the needs of production and life, people have long applied plant fibers to improve the engineering properties of soil. With the invention of lime, lime became a soil improvement material. Since the invention of cement, cement soil has gradually gained people's attention due to its excellent reinforcement effect. Because lime soil and cement soil have good mechanical properties and water stability, and have a certain degree of frost resistance, they are widely used in the construction of roads, ports, airports and other projects. [0003] Some special soils in nature have low strength, unstable properties, expansion and contraction when exposed to water and dehydration, and cannot be directly used as filling materials...
