Preparation and application method of a cement-free bulk industrial solid waste high-performance soil stabilizer

Abstract

The invention relates to a cement-free bulk industrial solid waste high-performance soil curing agent, which is composed of specially treated steel slag, water slag, waste rock powder, desulfurized gypsum, phosphogypsum slag, carbide slag and zeolite. The performance of the soil stabilizer of the invention is better than that of conventional soil stabilizers, and is beneficial to the improvement of engineering quality and the reduction of cost. The invention not only solves the problems of land occupation, environmental pollution, resource idleness and waste caused by the accumulation of existing bulk industrial solid waste, but also effectively replaces the amount of cement and clinker in conventional soil curing agents, equivalently reducing the amount of cement and the energy consumed in clinker production, the damage to nature and the CO produced 2 and other harmful gas emissions, and at the same time play a role in treating waste with waste. As in China, the product of the present invention is used to partially replace conventional products, which can reduce the explosives, coal consumption and power consumption of Kaishan blasting rocks every year, and reduce CO 2 The emission of harmful gases such as gas reaches hundreds of millions of tons, which is of great significance to improving my country's economic, social and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of building materials. More specifically, the invention relates to a cement-free bulk industrial solid waste high-performance soil stabilizer. Background technique [0002] From the various soil curing agents currently in use in China, whether they are solid and liquid in terms of form, or inorganic, ionic, and organic polymeric curing agents in terms of material composition, they are ubiquitous. There are several major bottlenecks: First, for various soil properties, it is often considered single-targeted and not compatible enough. One key only opens one lock, and only a small amount of compatibility is considered, but it is often difficult to take care of the needs of all parties, thus affecting the application range and effect of the soil stabilizer; second, the compressive strength of the stabilized soil The flexural strength is not high enough, most of them have just reached the standard, and some eve...

[0002] From the various soil curing agents currently in use in China, whether they are solid and liquid in terms of form, or inorganic, ionic, and organic polymeric curing agents in terms of material composition, they are ubiquitous. There are several major bottlenecks: First, for various soil properties, it is often considered single-targeted, and the compatibility is not enough

When encountering soil with high water content and high organic matter content, the strength of the soil after curing is often low, and traditional curing agents such as cement or clinker, fly ash, lime, and gypsum are used, and the water formed during the curing process The chemical products cannot effectively fill the internal pores of the soil. After the curing is completed, there are still a large number of pores in the structure. The water stability and durability are poor, and shrinkage and cracking are prone to occur.

The reason for these situations is that the best formula and best process have not been found

Sixth, conventional curing agents are expensive

Transporting, crushing and firing clinker consumes energy and pollutes the environment
