Plant-growing ecological concrete

Abstract

The invention discloses a plant-growing ecological concrete. The raw material of the plant-growing ecological concrete comprises the following components by weight: 400-500 parts of recycled concrete aggregate, 100-120 parts of ordinary Portland cement, 20-30 parts of dodecylbenzene sodium sulfonate, 10-20 parts of sodium nitrite antifreezing agent, 5-10 parts of vinyl acetate-vinyl chloride copolymer, 0.03-0.08 part of polycarboxylate superplasticizer, 5-15 parts of low-base-number synthetic calcium alkyl benzene sulfonate, 10-20 parts of oleic acid, 5-15 parts of methacrylic acid, 10-20 parts of water-absorbent resin, 3-10 parts of foam stabilizer, and 60-80 parts of water; honeycomb shaped gaps are formed to be beneficial for growing plant roots and providing a storage space for nutrients necessary for vegetation growth, the plant-growing ecological concrete achieves high strength, stability and durability, the various components produce a synergistic effect, the PH value of a hydration paste of a cement is reduced while the strength of the ecological concrete is guaranteed, the PH is close to neutrality, the compatibility of the ecological concrete with the plant is good, the compressive property is strong, the compressive effect is good, the compressive duration is long, and the ecological concrete is not qualitatively changed.

Description

technical field [0001] The invention relates to an ecological concrete, in particular to a planting ecological concrete. Background technique [0002] Ecological concrete is also called porous concrete. The Japan Concrete Engineering Association put forward the concept of porous concrete in 1995: the so-called porous concrete refers to a kind of special concrete material, which has special structure and surface characteristics, can adapt to biological growth, and plays an important role in regulating ecological balance, beautifying the environment, and realizing Harmony between humans and nature has a positive effect. Due to its porous structure, good rainwater permeability, sound absorption, and suitable for the growth of herbaceous plants, ecological concrete has been used in river landscape slope management and landscaping. With the popularization and application of ecological concrete, there are also some problems, especially in the application process of building exte...

Problems solved by technology

With the popularization and application of ecological concrete, there are also some problems, especially in the application process of building exterior structures, parking lots, sidewalks, squares, parks, roads, river revetments and greening substrates. First of all, the porous structure of ecological concrete , affecting its mechanical strength, especially its compressive performance. It is generally accepted in the industry that porosity and compressive strength are a set of contradictions. How to break this set of contradictions and find a new balance point is the future research direction, that is, to have a good At the same time, it can have high compressive strength; and in practical applications, it is also found that: (1) Ecological concrete is a brittle structure with low flexural and flexural properties, which cannot reach the external structure of buildings, parking lots, The pavement application needs of sidewalks, squares, parks, roads, river bank revetments and green substrates; (2) Whether the mechanical strength of ecological concrete has greater damage and damage after alkali reduction treatment; therefore, although ecological concrete has many Ordinary concrete does not have many advantages, but ecological concrete has two major defects: one is that its strength is lower than ordinary concrete, and the other is poor durability.
