Problems solved by technology

[0002] Traditionally, general concrete is used as pavement for paved roads, sidewalks, park squares or hillsides. Because general concrete has compact and hard high-density characteristics, almost no porosity, and lack of water permeability, after paving to form the pavement, Although it is very strong and durable, it is not suitable for creating a vegetative environment at all, let alone achieve the effect of a vegetative green environment, nor can it be applied to the fields of green building materials, green buildings, base water retention, vegetative pavement or sky gardens

Embodiment 1

[0034] Such as figure 1 As shown, the weight ratio range of each component of plant-grown permeable concrete is as follows:

[0035] (1) Cement 1;

[0036] (2) Hearthstone 0.3-0.4;

[0037] (3) Silica fume 0.2-0.3;

[0038] (4) Quartz sand 1.5-2.0;

[0039] (5) coarse aggregate 10-13;

[0040] (6) superplasticizer 0.03-0.05;

[0041] (7) Water 0.23-0.3.

[0042] Mix the cement, furnace stone, silica fume, quartz sand, superplasticizer and water in the above ratio first, and perform the first mixing by a frequency-variable mixer (commonly known as a barrel mixer) to obtain a low-water Mortar with special rubber ratio (that is, high-concentration cement); then mix the mortar with the above-mentioned proportion of coarse aggregate (10-13), and carry out the second mixing by a drum mixer (commonly known as a gyro mixer). Mixing, the vegetable permeable concrete with high porosity and high compressive strength can be obtained.

Embodiment 2

[0044] When mixing and preparing plant-grown permeable concrete, the preferred weight ratio of each component is as follows:

[0045] Cement: furnace stone: silica fume: quartz sand: coarse aggregate: superplasticizer: water = 1: 0.33: 0.26: 1.8: 11: 0.04: 0.28.

[0046] The mixing steps are the same as in Example 1.

Embodiment 3

[0048] Such as figure 2 As shown, when the vegetation permeable concrete is paved, the pavement should be rolled and tamped first, and after it is hardened, the soil and seeds should be spread, so as to create an excellent vegetation environment and achieve the function of greening the environment. The vegetative permeable concrete has a high water permeability function, and can reduce the latent heat of the environment through the effect of vegetative growth and water permeability, effectively reduce the ambient temperature of cities or regions, and solve the heat island effect.

[0049] The plant-grown permeable concrete is also very suitable for green building materials, green buildings, base water retention, paved roads, park squares, sky gardens or general pedestrian walkways, roof rainwater recovery systems and hillsides, etc. as pavements for permeable layers.

[0050] The soil laid in this example is composed of clay and cultivation soil in a ratio of 1:1. But this r...

Abstract

The invention relates to plant-growing permeable concrete, a blending method and application thereof. The plant-growing permeable concrete is formed by mixing cement, hearthstone, silica fume, quartz sand, coarse aggregates, a plasticizer and water in a specific weight ratio. The blending method comprises the following steps of: during blending, mixing the cement, the hearthstone, the silica fume, the quartz sand, the plasticizer and the water, and blending for the first time by using a variable frequency blender to prepare mortar with low water-binder ratio; and mixing the mortar and the coarse aggregates in a preset ratio, and blending for the second time by using a drum-type blender to prepare the plant-growing permeable concrete with high porosity and compression strength. The plant-growing permeable concrete is suitable to be used as the pavements of permeable layers, and after the pavements are rolled, tamped and hardened, soil is paved and seeds are sown so as to build the plant-growing environment and provide the function of environmental greening.

Description

technical field [0001] The invention relates to a planting permeable concrete and its mixing method and application, in particular to a planting permeable concrete with high porosity and high compressive strength and its mixing method and application. Background technique [0002] Traditionally, general concrete is used as pavement for paved roads, sidewalks, park squares or hillsides. Because general concrete has compact and hard high-density characteristics, almost no porosity, and lack of water permeability, after paving to form the pavement, Although it is very strong and durable, it is not suitable for creating a vegetative environment at all, and it is even more impossible to achieve the effect of a vegetative green environment, nor can it be applied to the fields of green building materials, green buildings, base water retention, vegetative pavement or sky gardens. Contents of the invention [0003] The main purpose of the present invention is to provide its mixing ...
