Soil curing agent formulation, powder soil curing agent formulation

Soil curing agent is a new type of energy-saving and environmentally friendly engineering material synthesized by a variety of inorganic and organic materials to solidify various types of soil. For the soil to be reinforced, according to the physical and chemical properties of the soil, only a certain amount of curing agent needs to be added, and the required performance indicators can be achieved after mixing and compaction.

It is characterized by excellent road technical indicators, low project cost, convenient construction, and shortened construction period, especially conducive to ecological and environmental protection. The use of soil curing agent can replace a large number of lime, cement, fly ash, gravel, gravel and other traditional road construction materials, save resources, energy, save land, protect vegetation, greatly reduce carbon dioxide and other greenhouse gas emissions, is conducive to ecological environmental protection, economic and environmental benefits are particularly obvious, is one of the innovative transportation technologies for the sustainable development of highway engineering.

Because it has better performance and economic and environmental benefits than traditional cement, lime and other soil curing materials. It can also solve some special problems that cement, lime, fly ash and other cementitious materials are difficult to solve when soil reinforcement, has a unique soil solidification effect and wide practicability, and has been widely used in the construction of highway base and subbase, water conservancy slope protection and other projects.

What material is the soil curing agent made of? What is the recipe for the production method of soil curing agent?

Soil activator is a microbial agent that improves soil, prevents compaction, and increases mechanism, which can be used in pots or ground to improve soil.

Soil activator is a general term used to describe a variety of products that can be added to soil to improve soil structure and increase plant productivity. Soil is a complex mixture of clay or sand, organic matter, beneficial bacteria and fungi, and chemicals such as oxygen, hydrogen, and carbon.

The principle of action of soil activators

1. Break the surface tension of water in the soil.

Quickly soak the surface layer of the soil, let the water infiltrate, so as to loosen the soil, break the compaction, and deepen the tillage layer.

2. Some products are rich in hydrophilic groups, after use, the organic matter in the soil will absorb water and expand, and the soil particles will lose water and shrink, at this time, the soil particles will be combined with the organic matter glue to form a water-stable aggregate structure (adjust the soil three comparisons), and the relationship between water, fertilizer, heat and gas in the soil can also be improved.

3. Some products contain more functional groups, which can increase the number of colloids in the soil, improve the ability to retain water and fertilizer and the utilization rate of fertilizer, and reduce the leaching runoff loss of fertilizer.

4. After using soil activator, it is beneficial to fully dissolve humic acid.

Promote the activity and reproduction of beneficial microorganisms, reduce toxic substances in the soil, and degrade nitrates.

Reduce pesticide residues and reduce the chance of harmful bacteria infection.

The formula ratio (weight) of soil curing agent is tricalcium silicate 3CAO·SIO272-79 tricalcium aluminate 3CAO·AL2O313-15 tetracalcium iron-aluminate 4CAO·AL2O3FE2O37-9 free calcium oxide CAO (free) 1-4 The manufacturing method of soil curing agent described in the present invention is that limestone, gypsum, clay, bauxite and fluorite are mixed first, then sintered at high temperature, and finally ball-ground into powder; The production process steps of soil curing agent are as follows: a, 85-87 parts of limestone (weight parts), 3-4 parts of gypsum, 8-9 parts of clay, 1 part of bauxite, and 1 part of fluorite are evenly mixed; b. Make the above mixture sintered at a temperature of at least about 1400 hours; c. The material ball obtained by step poly B is ground into a powder form of 250-300 mesh, and the soil curing agent is made. The use method of soil curing agent described in the present invention is in that after taking clay 60-70, natural sand 30-40 evenly mixed at the construction site, then adding 180-200kg of soil curing agent per cubic meter of mixed soil and mixing well, and then adding water to apply pressure to form.

Question: Is there any other way to make these information available online?

Dear, that's the only way.
