Abstract

The invention discloses a plant-growing cement soil ecological restoration substrate. The plant-growing cement soil ecological restoration substrate is prepared from the following components in partsby weight: 95-105 parts of planting soil, 4.5-5.5 parts of cement, 4-6 parts of phosphogypsum powder, 0.2-0.8 part of titanium gypsum powder, 0.6-1.2 parts of fluorogypsum powder, 1-3 parts of silicasol, 0.2-0.8 part of polylactic acid, 0.4-0.8 part of a polycarboxylic acid efficient water reducing agent, 8-11 parts of an organic material, 5.5-6.5 parts of a plant-growing cement soil activator, 2.25-2.75 parts of biochar, 1.5-2.5 parts of fibers and 1.6-2.2 parts of polyacrylamide. According to the plant-growing cement soil ecological restoration substrate and a preparation method thereof, the problems that the material utilization rate is low and industrial waste residue cannot be effectively utilized, the physical and chemical properties between various industrial by-products or industrial waste are utilized, a large amount of the industrial waste such as phosphogypsum can be consumed, the use amount of cement in a product can also be decreased, and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of slope ecological protection, in particular to a planting cement-soil ecological restoration substrate and a preparation method thereof. Background technique [0002] Large-scale engineering construction has brought unprecedented pressure on the environment where the project is located, leading to a series of ecological and environmental problems such as increased soil erosion, weakened water conservation function, reduced biodiversity, and uncoordinated landscape in the disturbed area of ​​the project, which seriously hindered the disturbance of the project. Sustainable development of landscape and environment in the surrounding area. At present, a variety of ecological slope protection technologies have been widely used in the ecological management of engineering slopes, and have achieved good social and ecological benefits. [0003] Vegetation concrete ecological protection technology can effectively take into a...
