Problems solved by technology

In many areas, waste clay is reused as backfill, but waste clay backfill often affects the environment due to defects such as domestic waste, corrosive components, and high water content in waste clay, and it is easy to cause ground depressions
In addition, due to the limited landfill and reclamation area, the landfill of waste clay occupies valuable land resources and destroys the soil structure, resulting in decreased food production, water pollution, land degradation, etc.

Abstract

The invention discloses ecological planting ceramsite and a preparation method thereof. The ecological planting ceramsite is prepared from the following raw materials: clay, a geopolymer cementing material, a liquid excitant, water, a nutrient substrate, an organic binder and alkali-resistant grass seeds, fully and uniformly mixing the pretreated clay, the geopolymer cementing material, the nutrient substrate and the grass seeds to obtain a mixture; spraying a mixed aqueous solution of a liquid excitant and an organic binder into the obtained mixture, uniformly stirring and mixing, granulating, and maintaining to obtain the ecological planting ceramsite. The ecological planting ceramsite does not need a sintering process, compared with sintered ceramsite, the non-sintered ceramsite has theadvantages of being high in water absorption rate, resistant to salt corrosion, good in durability and the like, meanwhile, the strength is high, the mass is light, the durability is good, and grassseeds in the ceramsite can grow under the conditions of proper sunlight, moisture and temperature. The baking-free ecological planting ceramsite is energy-saving and environment-friendly, and solid wastes such as waste clay are effectively utilized.

Description

Technical field[0001]The invention relates to the technical field of resource utilization of waste clay, in particular to an ecological planting ceramsite and a preparation method thereof.Background technique[0002]Abandoned clay refers to clay that cannot be directly used or whose function is degraded due to mining, industrial and construction activities, occupation of domestic garbage, pollution, and damage caused by natural disasters. Many areas currently re-use waste clay as backfill. However, the backfill of waste clay often affects the environment due to defects such as domestic garbage, corrosive components, and large water content in the waste clay, and it is also easy to cause ground depression. In addition, due to the limited landfill and reclamation area, the landfill of waste clay takes up valuable land resources and destroys the soil structure, resulting in a decline in food production, water pollution, and land degradation. With the expansion of industrial production an...
