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 an ecological planting ceramsite and a preparation method thereof. The raw material ecological planting ceramsite includes: clay, geopolymer gelling material, liquid activator, water, nutrient matrix, organic binder and alkali-resistant grass seeds ; Fully mix the pretreated clay, geopolymer cementitious material, nutrient matrix and grass seeds to obtain a mixture; spray the mixed aqueous solution of liquid activator and organic binder into the obtained mixture, stir and mix well and then granulate and maintain the ecological planting ceramsite. The ecological planting ceramsite does not require a sintering process. Compared with the sintered ceramsite, the unfired ceramsite has the characteristics of higher water absorption, salt corrosion resistance, and good durability. At the same time, it has high strength, light weight, and good durability. Under the conditions of suitable moisture and temperature, the grass seeds in the ceramsite can grow. The burning-free ecological planting ceramsite is energy-saving and environment-friendly, and enables solid waste such as waste clay to be 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 has degraded functions due to mining, industrial and construction activities, excavation damage, domestic garbage occupation, pollution and natural disaster damage. In many areas, discarded clay is reused as backfill. However, the backfill of discarded clay often affects the environment due to defects such as domestic garbage, corrosive components, and high water content in the discarded 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. With the expansion of indust...
