Soil stabilizer and preparation method thereof

Abstract

The invention provides a soil stabilizer. The soil stabilizer is prepared from, by mass, 52-65 parts of superfine slag powder, 10-15 parts of limestone powder, 5-10 parts of gypsum, 2-4 parts of short steel fibers, 7-15 parts of an additive and 0.5-1 part of a surfactant, wherein the additive is prepared from calcium carbonate, isopropanolamine and glycol. According to the soil stabilizer, the grain fineness levels of all components are different, the components are mixed mutually and act in synergism, the grain composition state is better, gaps in concrete are filled at different degrees, and the performance of concrete is improved; by adding the short steel fibers, the toughness of the soil stabilizer can be remarkably improved, and the problem that a traditional solidifying material is likely to crack is solved; besides, the soil stabilizer is high in compressive strength, and the compressive strength of the soil stabilizer is higher than that of a common stabilizer by 10 times or above; the soil stabilizer has excellent anti-seepage and anti-freezing performance; meanwhile, the strength and durability of soil can be greatly improved, and a preparing method is simple, low in cost and high in popularization value.

Description

technical field [0001] The invention relates to the technical field of building materials engineering, in particular to a soil curing agent and a preparation method thereof. Background technique [0002] With the development of society and the increase of engineering construction, cementitious materials are also developing rapidly. Due to the low cost and simple construction of lime soil and cement soil, they have been widely used in some water conservancy projects and agricultural projects. But in practice, it is found that the early strength of lime reinforcement is low, and the strength develops slowly; cement reinforcement shrinks a lot and is easy to crack. Therefore, soil curing agent is widely used. [0003] Soil stabilizer is a new type of energy-saving and environmentally friendly engineering material synthesized from various inorganic and organic materials to solidify various soils. Under the action of external pressure, the distance between soil particles will shr...

AI Technical Summary

Problems solved by technology

[0004] Because the traditional soil curing agent cannot meet the needs of the project in terms of durability, and has disadvantages such as low strength, no good crack resistance, and poor frost resistance, there is an urgent need for a soil stabilizer with fast consolidation speed and high early and late strength. , a soil stabilizer that improves soil durability and compaction
