Problems solved by technology

In the slope greening technology, using ordinary concrete as the sprayed base material has good firmness, but ordinary concrete does not have the environment for plant growth, which limits the growth of plants. Using pure soil as the sprayed base material instead of concrete is beneficial to plant growth However, the firmness is limited

Abstract

The present invention discloses a concrete additive, said additive is mainly formed from mineral powder containing elements of iron, phosphoruc, calcium and silicone, water-retaining agent and composite fertilizer. Said additive can be added in concrete, it not only provides rich nutrients for growth of concrete, it not only provides rich nutrients for growth of plant in concrete, but also can change concrete property so as to provide growth environment for plant in the concrete, so that it is favorable for greening slope land.

Description

technical field [0001] The invention relates to a concrete additive used for greening rock slopes. Background technique [0002] In the construction of highways, railways, water conservancy, electric power, mines and other projects, it is often necessary to excavate a large number of slopes. The development of the slopes destroys the original vegetation cover, resulting in a large amount of bare land and causing a series of ecological environment problems. . Such as soil erosion, landslides, mudslides, deterioration of local microclimate, and destruction of biological chains. Traditional slope protection methods, such as mortar block stones, dry rubble stones, prefabricated concrete blocks, and sprayed concrete, have a good effect on reducing the instability of the slope at the initial stage of new construction, but cannot solve the problem of restoring the ecological environment. Concrete greening technology can not only solve the problem of shallow slope protection, but ...
