In China's sustainable development strategy, energy conservation and emission reduction are an important direction for economic and social development. The "Guiding Opinions on Promoting the Healthy and Orderly Development of the Sand and Stone Industry" jointly issued by the five ministries and commissions supports the comprehensive utilization of waste rock tailings. Encourage and support the comprehensive utilization of waste rock, slag and tailings and other sand and gravel resources to achieve "turning waste into treasure"; encourage the use of solid waste resources to make recycled sand and gravel.

In recent years, environmental protection storms have gradually been set off in many parts of the country. To protect the green waters and green mountains, most areas of the country have banned mountains and rocks, rivers and sands. The raw materials necessary for these projects are seriously in short supply and prices have skyrocketed.

At the same time, during the "Eleventh Five-Year Plan" period, 11 billion tons of waste soil and slag were generated in my country's construction, and the figure is rising with the economic and social development. Removal of solid wastes such as construction waste also consumes a lot of manpower and material resources, which brings a great burden to corporate finance and government management.

The new round of large-scale infrastructure construction brings not only opportunities to the construction industry and its related industries, but also huge problems: where does the spoil go and where does the sand come from?

For this reason, we have researched and proposed the use of curing agents to solidify various waste soils and construction wastes, so as to effectively form new environmental protection engineering materials and apply them to pavement base, subbase and soft foundation treatment.

The application principle of the curing agent is the use of high molecular polymer particle technology, and the long-term copolymerization chain will form a durable waterproof semi-flexible solid matrix structure after contacting the soil, changing the nature of soil expansion and water absorption, making the soil permanent solidification, which conforms to the golden rule of soil solidification. This effect makes the structure layer built with soil as the raw material have higher strength in the early stage, stable growth in the later stage, and extremely strong water resistance. Therefore, it can fundamentally improve the tightness of road construction, solve the problems of road embrittlement, cracking, and frosting, extend the life of the roadbed, and open up a new way for the application of natural soil in road engineering.

Compared with the performance of traditional materials, the new soil curing agent has the following characteristics: stronger compressive strength and water resistance, and the unconfined compressive strength of mixtures of different proportions can reach 2.5-15.4MPa for 7 days. The strength of the stone stabilized material is equivalent, and the deflection value can also reach the standard of water stability.

The solidified soil is more low-carbon and environmentally friendly. It can digest the spoil and silt generated by the project on the spot, reducing the amount of materials such as gravel and gravel soil, and the construction speed is fast, which greatly reduces the overall cost of the project.

The soil curing agent produced by the company has passed the identification of the National Center for Disease Control and Inspection. The material itself is non-toxic and harmless, will not pollute the environment, and the land restoration is more convenient. Compared with traditional inorganic bonding materials, after the solidified soil is used as a temporary road, it can be directly used for re-cultivation after being broken by ordinary machinery.

It is the consensus of the whole society to prevent pollution and protect the environment, and the government management is constantly increasing. The new materials launched by our company conform to the social trend, which is non-polluting and reduces the pollution of waste to the environment, and contributes to the cause of environmental protection. . New materials can be used in many industries such as construction and environmental protection, civil and military applications, and inland borders and other environments to meet various customer needs.
