Problems solved by technology

[0006] But above-mentioned vegetation concrete has following shortcoming: 1) adopt a large amount of cements as the main cementing material of concrete, and cement can produce high strong alkalinity after meeting water hydration, thereby negatively affects the growth of plants; 2) concrete strength is low , cannot resist long-term rain erosion; 3) Add adhesive powder or "polymer glue" such as polyacrylamide. The rubber powder is water-soluble and will become soft during maintenance and watering. , resulting in loose spraying soil layer in the later stage, and it is easy to fall off in case of heavy rain; 4) The formula is complex and the cost of raw materials is high

Embodiment 1

[0023] A kind of concrete suitable for plant growth, 1) firstly carry out batching according to the following raw materials, 50 parts of clay, 20 parts of fly ash, 10 parts of cementitious material, 10 parts of sawdust, 8 parts of fermented organic fertilizer, 1 part of superphosphate , 1 part of water-retaining resin, wherein the cementitious material comprises 70% of gypsum, 20% of blast furnace slag, and 10% of low-alkali sulfur-aluminum cement, fully stirred evenly for subsequent use; For batching, first pour the concrete mixture into the mixing equipment and add a certain amount of grass seeds, add half of the water for mixing, and then add the remaining water for full mixing; 3) Prepare the prepared concrete according to the design requirements. Concrete construction, regular water maintenance.

Embodiment 2

[0025] A kind of concrete suitable for plant growth, 1) First, the ingredients are prepared according to the following raw materials: 80 parts of clay, 10 parts of fly ash, 5 parts of cementitious material, 2 parts of sawdust, 2 parts of fermented organic fertilizer, and 0.5 part of superphosphate , 0.5 part of water-retaining resin, wherein the cementitious material comprises gypsum 70%, blast furnace slag 20%, low-alkali sulfur-aluminum cement 10%, fully stirred evenly for standby; For batching, first pour the concrete mixture into the mixing equipment and add a certain amount of grass seeds, add half of the water for mixing, and then add the remaining water for full mixing; 3) Prepare the prepared concrete according to the design requirements. Concrete construction, regular water maintenance.

Embodiment 3

[0027] A kind of concrete suitable for plant growth, 1) firstly carry out batching according to the following raw materials, 60 parts of clay, 20 parts of fly ash, 10 parts of cementitious material, 5 parts of sawdust, 5 parts of fermented organic fertilizer, 0.01 part of superphosphate , 0.01 part of water-retaining resin, wherein the cementitious material comprises gypsum 70%, blast furnace slag 20%, low-alkali sulfur-aluminum cement 10%, fully stirred evenly for standby; For batching, first pour the concrete mixture into the mixing equipment and add a certain amount of grass seeds, add half of the water for mixing, and then add the remaining water for full mixing; 3) Prepare the prepared concrete according to the design requirements. Concrete construction, regular water maintenance.

Abstract

The invention discloses a cementing material, and concrete suitable for plant growth. The concrete comprises the following components in parts by mass: 50-80 parts of clay, 10-20 parts of fly ash, 5-10 parts of the cementing material as described in claim 1, 2-10 parts of sawdust, 2-8 parts of a fermented organic fertilizer, 0.1-1 part of calcium superphosphate and 0.1-2 parts of water-retaining resin, wherein the cementing material comprises 70% of gypsum, 20% of blast furnace slag and 10% of low-alkali sulphoaluminate cement. According to the concrete in the invention, a combination of the gypsum, the blast furnace slag and a small amount of the low-alkali sulphoaluminate cement is adopted to replace common Portland cement as the cementing material, so generation of strong alkali and useof rubber powder can be avoided, and the anti-scouring strength of the concrete is improved; a part of generated alkalinity can be consumed through a reaction of the fly ash, the blast furnace slag and a small amount of the low-alkali sulphoaluminate cement, so a neutral environment suitable for plant growth is created; and the strength of the vegetation concrete is improved through the synergistic effect of gypsum.

Description

technical field [0001] The invention relates to building concrete, in particular to a gel material and concrete suitable for plant growth. Background technique [0002] At present, as the requirements for the environment are getting higher and higher, local greening of urban buildings, coastal and revetment projects, and large-scale civil engineering projects such as roads and airport constructions all need to consider greening measures, among which guest soil spraying is one of them. That is, a thin layer of foreign soil is laid on the surface of the concrete to provide space for plant seeds to germinate, and to supply the nutrients needed for the initial growth of plants after germination to enhance the landscape and adjust the ecological balance. How to make vegetation grow well on the concrete surface has become a long-term research topic for vegetation concrete. [0003] In the existing research, such as the patent CN 201711386632.6 discloses a plant-growing porous con...
