Thick layer of self leveling aggregate used for fine aggregate of 40-120 mesh. Experiments show that the fine aggregate of 40-120 mesh has the advantages of good fluidity and strong particle suspension, which is conducive to the improvement of self-leveling fluidity and strength. With the development of industrial production, the amount of industrial waste is huge, the variety is wide, the composition is complex, and the treatment is quite difficult.

Thick layer of self leveling aggregate used for fine aggregate of 40-120 mesh. Experiments show that the fine aggregate of 40-120 mesh has the advantages of good fluidity and strong particle suspension, which is conducive to the improvement of self-leveling fluidity and strength. With the development of industrial production, the amount of industrial waste is huge, the variety is wide, the composition is complex, and the treatment is quite difficult. The resource utilization of industrial solid waste has become an important way to effectively alleviate the contradiction of strategic resource shortage. At the same time, the resource utilization of industrial solid waste is also an important way to alleviate the shortage of resources in China, reduce the pressure of resources on economic development, and effectively alleviate the pollution of China's ecological environment. In the selection of aggregate, the preference is given to the use of steel slag, steel mud, tailings slag and other solid waste production of spherical aggregate as a self-leveling aggregate, can make the industrial solid waste contained in the recyclable resources into waste.


2, steel slag, desulfurization gypsum production thick layer self leveling

This product is mainly used for ground leveling and backfilling of buildings. The market usage is huge. The product can use 90% of the waste slag discharged from steel mills. The project has been signed with Laigang Group for trial and has been applied in major real estate.

Processing desulfurization gypsum or phosphogypsum into self-leveling material technology can provide a technical route for realizing large-scale and resource utilization of flue gas desulfurization gypsum, realize the ecological closure of flue gas desulfurization, and promote the healthy development of flue gas desulfurization in China. On the one hand, it can greatly reduce the land occupation and stacking cost of desulfurization gypsum, on the other hand, it can make up for the blank of natural gypsum resources in some areas, which is conducive to promoting the development of gypsum building materials and enriching gypsum varieties, promote the development of self-leveling materials. FGD gypsum is converted into self-leveling material, which eliminates the secondary pollution of FGD gypsum and has the characteristics of circular economy.

Thick layer self-leveling main raw materials are cementitious materials, aggregates, additives and other components. The cementitious material is mainly industrial by-product desulfurization gypsum, and the aggregate is solid waste, steel slag, steel mud, tailings slag, etc., which saves resources, turns waste into treasure, and has high economic benefits and good environmental benefits.
