Problems solved by technology

[0003] Although there are various types of porous concrete in the prior art, there are still defects in the current vegetation concrete, for example, there is no nutrient required for plant survival in the concrete, and the void ratio is small and irregular, which is not conducive to the planting of green plants. , these reasons have led to the technical defects of long planting cycle and inconvenient replacement of green plants after death

Embodiment 1

[0033] A method for preparing planting-type concrete with large voids reserved, comprising the steps of:

[0034] (1) Preparation of fermented coconut skin:

[0035] Coconut skin is pulverized and then bagged and added with water. The mass ratio of coconut skin and water is 1:0.5, and it is fermented at room temperature for 40d in a sealed state to obtain fermented coconut skin;

[0036] (2) Weighing: Weigh raw materials according to the following parts by weight: 80 parts of gravel; 20 parts of Portland cement; 0.5 parts of additives; 10 parts of fermented coconut skin; 5 parts of water, set aside;

[0037] The additive is mixed by 1 part of concrete surface enhancer, 3.1 parts of carboxylate, 0.8 part of sodium sulfate, and 1 part of iron sulfate;

[0038] (3) Mix crushed stone, Portland cement, additives, fermented coconut skin and water together, then put into the mold and form to obtain shaped concrete, and the shaped concrete is then cured to obtain planting type reserv...

Abstract

The invention relates to the technical field of concrete, in particular to planting type large-gap-reserved concrete as well as a preparation method and application thereof. The planting type reserved large-gap concrete is prepared from the following raw materials in parts by weight: 80-85 parts of gravel, 15-20 parts of Portland cement, 0.5-1 part of an additive, 5-10 parts of fermented coconut peel and 5-10 parts of water. The planting type large-gap-reserved concrete prepared from the fermented coconut peel can adsorb urban pollutant dust and reduce flying dust pollution, patterns and colors can be designed according to environmental and function requirements, the concrete can be fully combined with the surrounding environment, and the planting type large-gap-reserved concrete can be applied to protection and greening of urban tree pools and slope greening and protection of expressways, intercity railways, tailing dams and the like. According to the invention, a green, healthy and comfortable urban road is provided, the urban road can be compatible with the natural environment, harmonious coexistence of buildings and the environment is achieved, and sustainable development is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a planting-type concrete with large voids reserved and its preparation method and application. Background technique [0002] In order to reduce the environmental load and improve the ecological environment, a large number of experimental studies on porous concrete have been carried out at home and abroad for many years. Porous concrete is an ecological concrete with special pore structure and surface characteristics prepared by a special process. Concrete not only has a certain strength and good water permeability, but also can alleviate the pressure of a large amount of land resources occupied by construction waste, and has good ecological and economic benefits; the porous vegetation concrete prepared by using it can be applied to slope protection and pavement pavement In the construction of roof gardens, etc., it has produced good anti-scouring, flood control, and ecological r...
