Problems solved by technology

[0005] In the prior art, ordinary Portland cement is used as the cementitious material in the preparation of vegetation concrete. During the hydration process of vegetation concrete, strong alkali hydration products such as calcium hydroxide will be produced, resulting in a strong alkali environment, which is unfavorable to the environment for plant growth. It is not conducive to the early germination of plants and the long-term growth in the later period, and the plants will not germinate or the growth rate of the next year will be low.
In order to solve the above technical problems, the most commonly used methods are alkali-reducing admixture technology and mineral admixture technology. In the early stage of hydration, these methods cannot achieve the purpose of reducing alkali, and the cementitious material used in concrete is still ordinary Portland cement, and the production cost of concrete is relatively high

Abstract

The invention discloses a vegetation concrete, which comprises the following components by weight: 5-8 parts of low-alkalinity cementitious material, 3-5 parts of plant fiber, 0.02-0.05 part of cellulose ether, 40-60 parts of soil, organic fertilizer 20-40 parts of soil, 0.5-1 part of chemical fertilizer, 0.5-3 parts of grass seed, 10-20 parts of pottery sand, 20-30 parts of water. The invention also discloses the preparation method and application of the above-mentioned vegetation concrete. The vegetation concrete of the present invention is weak in alkalinity in the process of hydration, and can provide a suitable growth environment for plants; it can also reduce the phenomenon of cracking and falling off, and increase stability; and it has excellent fertilizer and water retention performance, providing plants with Excellent growing environment. The preparation method of the vegetation concrete of the invention is simple and easy to operate, and it can be applied to projects of ecological slope protection, side slope greening, isolation zone greening or mine greening.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a vegetation concrete and its preparation method and application. Background technique [0002] In the construction of highways, railways, water conservancy and other projects, it is often necessary to excavate a large number of slopes. The development of slopes will seriously damage the original vegetation cover, causing desertification, soil erosion, landslides and debris flows and other ecological environmental problems. The damaged ecosystem develops towards a virtuous cycle, and gradually restoring the health of the ecosystem has become an important task of ecological construction. [0003] Vegetation concrete is a new type of environmentally friendly material with remarkable ecological, landscape, slope protection and social benefits. It is suitable for popularization and application in the fields of road traffic, slope greening, water conservancy projects, etc. It can realize the o...
