Problems solved by technology

However, the addition of cement in ordinary concrete causes poor soil structure and easy hardening, and there is not enough air and water in the base material, which is not suitable for plant growth. The rate is low, and plants cannot be used to restore the ecology; and the hydration of cement is alkaline, which will increase the pH value, which is not conducive to the growth of plants
Due to the drought and low rainfall in Northwest China, and the serious salinization of the soil, the pH value of the soil is relatively high, so cement is used as the cement, because the cement produces Ca(OH) after hydration. 2 , the pH value is usually greater than 14, so the vegetation concrete using cement as the cement will further increase the pH value of the soil, which is not conducive to plant growth
[0005] (2) Using pure soil as the spray base material is suitable for plant growth, but the firmness between the spray base material and the slope is limited to a certain extent, and the strength and durability of the vegetation concrete layer cannot meet the requirements, and cannot be attached stably On the slope, when it is washed by rain or splashed, it cannot protect the slope

Abstract

The invention discloses vegetation concrete, which relates to the technical field of engineering and ecology and comprises the following components in parts by weight: 10-15 parts of ardealite, 3-6 parts of fly ash, 1-3 parts of superfine silica fume, 45-70 parts of nutrient loam, 5-10 parts of organic fertilizer, 1-3 parts of expanded perlite, 1-3 parts of xanthan gum, 2-3 parts of plant fiber, 1-2 parts of natural inorganic fiber material, 2-5 parts of vegetation modifier, 0.5-1 part of inorganic nano water-retaining agent. 0.1-0.3 part of a plant type air entraining agent and 1 part of plant seeds. The vegetation concrete provided by the invention integrates water permeability, air permeability, vegetation and scour prevention, can restore and regulate a small ecosphere, and balances the relationship between the concrete and plant growth.

Description

technical field [0001] The invention relates to the technical fields of engineering and ecology, in particular to a vegetation concrete. Background technique [0002] Vegetation concrete is a new type of mixed material, which plays a certain role in slope protection while providing natural conditions for vegetation to grow. At present, with the rapid development of social economy, the number of engineering construction projects has increased rapidly. In order to avoid slope collapse during engineering construction, it is necessary to carry out slope protection work, or to carry out ecological treatment and restoration after human damage, so the vegetation concrete ecological protection technology has been widely used. The core method of existing vegetation concrete is to mix concrete and plant seeds into a spray base material, and spray the mixture onto the side slope. This technology uses the bonding effect between the concrete and the slope and the fixing net technology ...
