Abstract

The invention belongs to the technical field of curing agents, and particularly relates to a high-humic-acid soil curing agent and a preparation method thereof. The high-humic-acid soil curing agent comprises substances in percentage by mass: 25%-40% of steel slag, 15%-25% of fly ash, 10%-15% of quick lime, 10%-20% of ordinary Portland cement, 6%-10% of an exciting agent, 1%-5% of an ion replacing agent, 1%-3% of a water repellent, 4%-6% of a retarder, 1%-2% of an early strength agent, 1%-3% of a filling agent, 1%-3% of a stabilizer, 1%-2% of an air entraining agent, 0.5%-1% of a water reducing agent and 0.5%-2% of a humic acid modifier. The high-humic-acid soil curing agent has the effects and advantages that the influence of humic acid on soil can be effectively reduced, the shear strength, the compressibility and the water stability of the soil are improved, the pore size, the compressibility and the permeability of the soil are reduced, and good economic and environmental benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of curing agent. In particular, it relates to a high humic acid soil stabilizer 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, and expansion and contraction when exposed to water and dehydration, so they cannot be directly used as filling materials for engineering constr...
