Abstract

The invention discloses an environmentally friendly soil curing agent and a preparation method. The environmentally friendly soil curing agent comprises 30 parts of papermaking sludge, 15 parts of slag powder, 32 parts of sodium polyacrylate, 36 parts of glycerol, 26 parts of sulfonated oil, 18 parts of an exciting agent, 9 parts of an oxidant, 10 parts of a dispersant, 2 parts of a polymeric additive, 0.6 part of a surfactant, 4 parts of lignin fiber, 10 parts of amino silanol, and 3-6 parts of a water absorbing agent. The environmentally friendly soil curing agent of the invention can be processed in a wide range, the hardness of obtained cured soil is in a high range, the obtained cured soil has the advantages of high durability, strong permeability and good water resistance, and the curing agent has the advantages of low production cost, environmental protection and no pollution.

Description

technical field [0001] The invention relates to the field of road construction. More specifically, the present invention relates to an environment-friendly soil stabilizer and a preparation method thereof. Background technique [0002] 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 building materials for engineering construction. With the rapid advancement of engineering construction, the demand for construction materials such as sand and stone is increasing, and the damage to the natural environment is becoming more and more serious, resulting in increasingly scarce sand and gravel resources. In addition, although traditional cement soil and lime soil have good strength, water stability and frost resistance, they have been widely used in many projects. However, cement soil tends to shrink greatly and has a high risk of cracking, while lime soil has...
